Data Fields |
uint32_t |
base_addr[kDtAesRegBlockCount] |
Base address of each register block. |
dt_clock_t |
clock[kDtAesClockCount] |
Clock signal connected to each clock port. |
top_darjeeling_alert_id_t |
first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler.
|
top_earlgrey_alert_id_t |
first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler.
|
dt_instance_id_t |
inst_id |
Instance ID. |
dt_reset_t |
reset[kDtAesResetCount] |
Reset signal connected to each reset port. |
◆ TRY_GET_DT
#define TRY_GET_DT |
( |
| dt, |
|
|
| default ) |
Value:({
if ((dt) < (
dt_aes_t)0 || (dt) >= kDtAesCount)
return (
default); &aes_desc[dt]; })
Return a pointer to the dt_aes_desc_t
structure of the requested dt
if it's a valid index.
Otherwise, this macro will return
(i.e. exit the function) with the provided default value.

◆ dt_aes_alert_from_alert_id()
Convert a global alert ID to a local aes alert type.
- Parameters
-
dt | Instance of aes. |
alert | A global alert ID that belongs to this instance. |
- Returns
- The aes alert, or
kDtAesAlertCount
.
Note: This function assumes that the global alert ID belongs to the instance of aes passed in parameter. In other words, it must be the case that dt_aes_instance_id(dt) == dt_alert_id_to_instance_id(alert)
. Otherwise, this function will return kDtAesAlertCount
.

◆ dt_aes_alert_to_alert_id()
Get the alert ID of a aes alert for a given instance.
Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.
- Parameters
-
dt | Instance of aes. |
alert | A aes alert. |
- Returns
- The Alert Handler alert ID of the alert of this instance.
Definition at line 80 of file dt_aes.c.
◆ dt_aes_clock()
Get the clock signal connected to a clock port of an instance.
- Parameters
-
dt | Instance of aes. |
clk | Clock port. |
- Returns
- Clock signal.
Definition at line 98 of file dt_aes.c.
◆ dt_aes_from_instance_id()
Get the aes instance from an instance ID.
For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3
.
- Parameters
-
- Returns
- A aes instance.
Note: This function only makes sense if the instance ID has device type aes, otherwise the returned value is unspecified.
Definition at line 60 of file dt_aes.c.
◆ dt_aes_instance_id()
Get the instance ID of an instance.
- Parameters
-
- Returns
- The instance ID of that instance.
Definition at line 67 of file dt_aes.c.
◆ dt_aes_reg_block()
Get the register base address of an instance.
- Parameters
-
dt | Instance of aes. |
reg_block | The register block requested. |
- Returns
- The register base address of the requested block.
Definition at line 72 of file dt_aes.c.
◆ dt_aes_reset()
Get the reset signal connected to a reset port of an instance.
- Parameters
-
dt | Instance of aes. |
rst | Reset port. |
- Returns
- Reset signal.
