18.2.1.22 ROM_SysCtlPeripheralReady
Determines if a peripheral is ready.
Prototype:
bool
ROM_SysCtlPeripheralReady(uint32_t ui32Peripheral)
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_SysCtlPeripheralReady is a function pointer located at ROM_SYSCTLTABLE[35].
Parameters:
ui32Peripheral is the peripheral in question.
Description:
Determines if a particular peripheral is ready to be accessed. The peripheral may be in a non-
ready state if it is not enabled, is being held in reset, or is in the process of becoming ready
after be enabled or taken out of reset.
