System Control
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_SYSCTLTABLE is an array of pointers located at ROM_APITABLE[13].
ROM_SysCtlPeripheralDeepSleepEnable is a function pointer located at
ROM_SYSCTLTABLE[10].
Parameters:
ui32Peripheral is the peripheral to enable in deep-sleep mode.
Description:
This function allows a peripheral to continue operating when the processor goes into deep-
sleep mode. Since the clocking configuration of the device may change, not all peripherals
can safely continue operating while the processor is in sleep mode. Those that must run at a
particular frequency (such as a timer) will not work as expected if the clock changes. It is the
responsibility of the caller to make sensible choices.
Deep-sleep mode clocking of peripherals must be enabled via
ROM_SysCtlPeripheralClockGating(); if disabled, the peripheral deep-sleep mode con-
figuration is maintained but has no effect when deep-sleep mode is entered.
The ui32Peripheral parameter must be only one of the follow-
ing values: SYSCTL_PERIPH_ADC0, SYSCTL_PERIPH_ADC1,
SYSCTL_PERIPH_CAN0, SYSCTL_PERIPH_CAN1, SYSCTL_PERIPH_CAN2,
