PM5358 S/UNI-4x622 Driver Manual

Application Programming Interface

Proprietary and Confidential to PMC-Sierra, Inc. 53

Document ID: PMC-2010419, Issue 1

Inputs None

Outputs None

Returns Success = SUNI4x622_SUCCESS

Failure = SUNI4x622_ERR_INVALID_MODULE_STATE

Valid States SUNI4x622_MOD_IDLE, SUNI4x622_MOD_READY

Side Effects Changes the MODULE state to SUNI4x622_MOD_START

Starting the Driver Module: suni4x622ModuleSta rt

This function connects the RTOS resources to the driver. This involves allocating semaphores and

timers, initializing buffers and installing the ISR handler and DPR task. Upon successful return

from this function the driver is ready to add devices.

Prototype INT4 suni4x622ModuleStart(void)

Inputs None

Outputs None

Returns Success = SUNI4x622_SUCCESS

Failure = SUNI4x622_ERR_INVALID_MODULE_STATE

SUNI4x622_ERR_MEM_ALLOC

SUNI4x622_ERR_INT_INSTALL

Valid States SUNI4x622_MOD_IDLE

Side Effects Changes the MODULE state to SUNI4x622_MOD_READY

Stopping the Driver Module: suni4x622ModuleStop

This function disconnects the RTOS resources from the driver. This involves de-allocating

semaphores and timers, freeing-up buffers and uninstalling the ISR handler and the DPR task. If

there are any registered devices, suni4x622Delete is called for each.

Prototype INT4 suni4x622ModuleStop(void)

Inputs None

Outputs None

Returns Success = SUNI4x622_SUCCESS

Failure = SUNI4x622_ERR_INVALID_MODULE_STATE

Valid States SUNI4x622_MOD_READY
