Function Documentation

void ICM_Configure

(

uint32_t

mode

)

Configures an ICM peripheral with the specified parameters.

Parameters:

mode

Desired value for the ICM mode register (see the datasheet).

Definition at line 153 of file icm.c.

void ICM_DisableIt

(

uint32_t

sources

Disables the selected interrupts sources on a ICM peripheral.

Parameters:

sources

Bitwise OR of selected interrupt sources.

Definition at line 171 of file icm.c.

void ICM_DisableMonitor

(

uint8_t

region

)

Disable region monitoring for given region.

Parameters:

region,When

bit RMDIS[region] is set to one, the monitoring of Region is disabled.

Definition at line 144 of file icm.c.

void ICM_EnableIt

(

uint32_t

sources

)

Enables the selected interrupts sources on a ICM peripheral.

Parameters:

sources

Bitwise OR of selected interrupt sources.

Definition at line 162 of file icm.c.

void ICM_EnableMonitor

(

uint8_t

region

)

Enable region monitoring for given region.

Parameters:

region,When

bit RMEN[region] is set to one, the monitoring of Region is activated.

Definition at line 134 of file icm.c.

uint32_t ICM_GetIntStatus

(

void

)

Get the current interrupt status register of the given ICM peripheral.

Returns:

ICM status register.

Definition at line 180 of file icm.c.

uint32_t ICM_GetStatus

(

void

)

void ICM_ReComputeHash

(

uint8_t

region

)

Recompute Internal hash.

Parameters:

region,When

REHASH[region] is set to one, the region digest is re-computed.

Note:

This bit is only available when Region monitoring is disabled.

Definition at line 124 of file icm.c.

void ICM_SetDescStartAddress

(

uint32_t

addr

)

Set descriptor area start address register.

Parameters:

addr

start address

Note:

The start address is a multiple of the total size of the data structure (64 bytes).
