System Control
ROM_SysCtlPeripheralSleepDisable
is a function pointer located at
ROM_SYSCTLTABLE[9]
.
Parameters:
ui32Peripheral is the peripheral to disable in sleep mode.
Description:
This function causes a peripheral to stop operating when the processor goes into sleep mode.
Disabling peripherals while in sleep mode helps to lower the current draw of the device. If en-
abled (via
ROM_SysCtlPeripheralEnable() ), the peripheral will automatically resume operation
when the processor leaves sleep mode, maintaining its entire state from before sleep mode
was entered.
Sleep mode clocking of peripherals must be enabled via ROM_SysCtlPeripheralClockGating() ;
if disabled, the peripheral sleep mode configuration is maintained but has no effect when 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 ,
