Function Description

void powerSignalProcessing(void)

Specification: Read power key press SWDD_PSP-001

is implemented by: SWIMPL_PSP-001

is tested by: TS_PSP-001

The function must check for the press of the power key.

Specification: Set power state to ON SWDD_PSP-002

is implemented by: SWIMPL_PSP-001

is tested by: TS_PSP-002

If the retrieved power state is POWER_STATE_OFF, the function shall set the power state to POWER_STATE_ON.

Specification: Set power state to OFF SWDD_PSP-003

is implemented by: SWIMPL_PSP-001

is tested by: TS_PSP-002

If the retrieved power state is not POWER_STATE_OFF, the function shall set the power state to POWER_STATE_OFF.
