Texas Instruments Tiva TM4C123GH6PM User Manual

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_SysCtlPeripheralDeepSleepDisable is a function pointer located at
ROM_SYSCTLTABLE[11].
Parameters:
ui32Peripheral is the peripheral to disable in deep-sleep mode.
Description:
This function causes a peripheral to stop operating when the processor goes into deep-sleep
mode. Disabling peripherals while in deep-sleep mode helps to lower the current draw of
the device, and can keep peripherals that require a particular clock frequency from oper-
ating when the clock changes as a result of entering deep-sleep mode. If enabled (via
ROM_SysCtlPeripheralEnable()), the peripheral will automatically resume operation when the
processor leaves deep-sleep mode, maintaining its entire state from before deep-sleep mode
was entered.
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,
