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
