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_SysCtlPWMClockSet is a function pointer located at ROM_SYSCTLTABLE[25].
Parameters:
ui32Config is the configuration for the PWM clock; it must be one of SYSCTL_PWMDIV_1,
SYSCTL_PWMDIV_2, SYSCTL_PWMDIV_4, SYSCTL_PWMDIV_8,
SYSCTL_PWMDIV_16, SYSCTL_PWMDIV_32, or SYSCTL_PWMDIV_64.
Description:
This function sets the rate of the clock provided to the PWM module as a ratio of the processor
clock. This clock is used by the PWM module to generate PWM signals; its rate forms the basis
for all PWM signals.
Note:
The clocking of the PWM is dependent upon the system clock rate as configured by
ROM_SysCtlClockSet().
Returns:
None.
18.2.1.29 ROM_SysCtlReset
Resets the device.
Prototype:
void
ROM_SysCtlReset(void)
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_SysCtlReset is a function pointer located at ROM_SYSCTLTABLE[19].
Description:
This function will perform a software reset of the entire device. The processor and all peripher-
als are reset and all device registers will return to their default values (with the exception of the
reset cause register, which will maintain its current value but have the software reset bit set as
well).
Returns:
This function does not return.
18.2.1.30 ROM_SysCtlResetCauseClear
Clears reset reasons.
Prototype:
void
ROM_SysCtlResetCauseClear(uint32_t ui32Causes)
