Detailed Description

Function Documentation

ICC_disable()

void ICC_disable

(

void

)

Disables ICC module.

This function disables ICC.

Returns

None

ICC_enable()

void ICC_enable

(

void

)

Enables ICC module.

This function enables ICC.

Returns

None

ICC_getCurrentICM()

uint8_t ICC_getCurrentICM

(

void

)

Gets the current interrupt compare mask.

Returns a 2-bit value that specifies the minimum interrupt priority level that will be sent for service. If ICM[1:0] is less than the priority level (ILSRx[1:0]) of the new interrupt, the corresponding source is sent to the CPU. Note that the ICMC is the element stack that the stack pointer is pointing to.

Returns

Minimum ICC interrupt priority level that will be serviced. Return one of the following:

• ICC_LEVEL_0
• ICC_LEVEL_1
• ICC_LEVEL_2
• ICC_LEVEL_3
• ICC_LEVEL_ERROR
  returns minimum interrupt level.

ICC_getICM0()

uint8_t ICC_getICM0

(

void

)

Gets the interrupt level at Interrupt compare mask virtual stack position 0.

Returns interrupt level of ICM virtual stack position 0 as a ready-to-read 8-bit integer value (automatically adjusted from original bit position.)

Returns

Interrupt level of ICM virtual stack position 0. Return one of the following:

• ICC_LEVEL_0
• ICC_LEVEL_1
• ICC_LEVEL_2
• ICC_LEVEL_3
• ICC_LEVEL_ERROR
  returns interrupt level of ICM virtual stack position 0.

ICC_getICM1()

uint8_t ICC_getICM1

(

void

)

Gets the interrupt level at Interrupt compare mask virtual stack position 1.

Returns interrupt level of ICM virtual stack position 1 as a ready-to-read 8-bit integer value (automatically adjusted from original bit position.)

Returns

Interrupt level of ICM virtual stack position 1. Return one of the following:

• ICC_LEVEL_0
• ICC_LEVEL_1
• ICC_LEVEL_2
• ICC_LEVEL_3
• ICC_LEVEL_ERROR
  returns interrupt level of ICM virtual stack position 1.

ICC_getICM2()

uint8_t ICC_getICM2

(

void

)

Gets the interrupt level at Interrupt compare mask virtual stack position 2.

Returns interrupt level of ICM virtual stack position 2 as a ready-to-read 8-bit integer value (automatically adjusted from original bit position.)

Returns

Interrupt level of ICM virtual stack position 2. Return one of the following:

• ICC_LEVEL_0
• ICC_LEVEL_1
• ICC_LEVEL_2
• ICC_LEVEL_3
• ICC_LEVEL_ERROR
  returns interrupt level of ICM virtual stack position 2.

ICC_getICM3()

uint8_t ICC_getICM3

(

void

)

Gets the interrupt level at Interrupt compare mask virtual stack position 3.

Returns interrupt level of ICM virtual stack position 3 as a ready-to-read 8-bit integer value (automatically adjusted from original bit position.)

Returns

Interrupt level of ICM virtual stack position 3. Return one of the following:

• ICC_LEVEL_0
• ICC_LEVEL_1
• ICC_LEVEL_2
• ICC_LEVEL_3
• ICC_LEVEL_ERROR
  returns interrupt level of ICM virtual stack position 3.

ICC_getInterruptLevel()

uint8_t ICC_getInterruptLevel

(

uint32_t

interruptSource

)

Gets ICC interrupt level for selected source.

This function gets ICC interrupt level given a maskable interrupt source.

Parameters
