ERR_CODE

This register holds information about error conditions that occurred in the agents interacting with the OTP macro via the internal bus. The error codes should be checked if the partitions, DAI or LCI flag an error in the STATUS register, or when an INTR_STATE.otp_error has been triggered. Note that all errors trigger an otp_error interrupt, and in addition some errors may trigger either an fatal_macro_error or an fatal_check_error alert.

Instances

Fields

{"reg": [{"name": "ERR_CODE", "bits": 3, "attr": ["ro"], "rotate": -90}, {"bits": 29}], "config": {"lanes": 1, "fontsize": 10, "vspace": 100}}

DIRECT_ACCESS_REGWEN . DIRECT_ACCESS_REGWEN

This bit controls whether the DAI registers can be written. Write 0 to it in order to clear the bit.

Note that the hardware also modulates this bit and sets it to 0 temporarily during an OTP operation such that the corresponding address and data registers cannot be modified while an operation is pending. The DAI_IDLE status bit will also be set to 0 in such a case.

CHECK_TRIGGER . CONSISTENCY

Writing 1 to this bit triggers a consistency check. SW should monitor STATUS.CHECK_PENDING and wait until the check has been completed. If there are any errors, those will be flagged in the STATUS and ERR_CODE registers, and via interrupts and alerts.

CHECK_TRIGGER . INTEGRITY

Writing 1 to this bit triggers an integrity check. SW should monitor STATUS.CHECK_PENDING and wait until the check has been completed. If there are any errors, those will be flagged in the STATUS and ERR_CODE registers, and via the interrupts and alerts.

Fields

{"reg": [{"name": "CHECK_TIMEOUT", "bits": 32, "attr": ["rw"], "rotate": 0}], "config": {"lanes": 1, "fontsize": 10, "vspace": 80}}

CHECK_TIMEOUT . CHECK_TIMEOUT

Timeout value in cycles for the for the integrity and consistency checks. If an integrity or consistency check does not complete within the timeout window, an error will be flagged in the STATUS register, an otp_error interrupt will be raised, and an fatal_check_error alert will be sent out. The timeout should be set to a large value to stay on the safe side. The maximum check time can be upper bounded by the number of cycles it takes to readout, scramble and digest the entire OTP array. Since this amounts to roughly 25k cycles, it is recommended to set this value to at least 100’000 cycles in order to stay on the safe side. A value of zero disables the timeout mechanism (default).

INTEGRITY_CHECK_PERIOD . INTEGRITY_CHECK_PERIOD

The pseudo-random period is generated using a 40bit LFSR internally, and this register defines the bit mask to be applied to the LFSR output in order to limit its range. The value of this register is left shifted by 8bits and the lower bits are set to 8’hFF in order to form the 40bit mask. A recommended value is 0x3_FFFF, corresponding to a maximum period of ~2.8s at 24MHz. A value of zero disables the timer (default). Note that a one-off check can always be triggered via CHECK_TRIGGER.INTEGRITY.

CONSISTENCY_CHECK_PERIOD

This value specifies the maximum period that can be generated pseudo-randomly. This applies to the LIFE_CYCLE partition and the HW_CFG* and SECRET* partitions once they are locked.

• Offset: 0xa4

• Reset mask: 0xffffffff
• Register enable: CHECK_REGWEN

The pseudo-random period is generated using a 40bit LFSR internally, and this register defines the bit mask to be applied to the LFSR output in order to limit its range. The value of this register is left shifted by 8bits and the lower bits are set to 8’hFF in order to form the 40bit mask. A recommended value is 0x3FF_FFFF, corresponding to a maximum period of ~716s at 24MHz. A value of zero disables the timer (default). Note that a one-off check can always be triggered via CHECK_TRIGGER.CONSISTENCY.

After a reset, write access to the PLAT_OWNER_AUTH_SLOT2 partition is locked and the digest becomes visible in this CSR.

• Reset default: 0x0
• Reset mask: 0xffffffff

SW_CFG_WINDOW

Any read to this window directly maps to the corresponding offset in the creator and owner software config partitions, and triggers an OTP readout of the bytes requested. Note that the transaction will block until OTP readout has completed.

• Word Aligned Offset Range: 0x4000to0x7ffc
• Size (words): 4096
• Access: ro
• Byte writes are not supported.
