Bits
Name
Description
0
Enable_ROT
Writing a ‘0’ to this bit will gate off the clock to the Rotator module, thus stopping
its operation
1
Enable_KPC
Writing a ‘0’ to this bit will gate off the clock to the Keypad Controller module,
thus stopping its operation
2
Enable_PWM
Writing a ‘0’ to this bit will gate off the clock to the PWM module, thus stopping
its operation
3
Enable_GPIO
Writing a ‘0’ to this bit will gate off the clock to the GPIO module, thus stopping
its operation
4
Sleep
Writing a ‘1’ to this bit will put the device in sleep mode. When in sleep mode, all
the units which need to work on clocks synchronous to 32KHz will get the clocks
derived from the 32K domain. The RC Oscillator will be shut off.
5
Disable_32KHz
Set this bit to disable the 32KHz OSC, thus putting the device in hibernate
mode. Only a Reset or a wakeup on IIC will reset this bit
6-
-
7
Soft_Reset
Writing a ‘1’ to this bit will do a soft reset of the device. Once the reset is done,
this bit will be cleared to ‘0’ by the HW.
