6.3.8.13
These bits select the alternate function for GPIOA4.
6.3.9
The Peripheral Clock Enable register is used to enable or disable clocks to the peripherals as a power
savings feature. The clocks can be individually controlled for each peripheral on the chip. The
corresponding peripheral should itself be disabled while its clock is shut off. IPBus writes cannot be made
to a module that has its clock disabled.
6.3.9.1
Each bit controls clocks to the indicated peripheral.
6.3.9.2
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.3.9.3
Each bit controls clocks to the indicated peripheral.
6.3.9.4
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.3.9.5
Each bit controls clocks to the indicated peripheral.

00 = Select PWM4 when peripheral mode is enabled in GPIOA4 (default)
01 = Select PWM4 when peripheral mode is enabled in GPIOA4
10 = Select FAULT1 when peripheral mode is enabled in GPIOA4
11 = Select T2 when peripheral mode is enabled in GPIOA4
0 = The clock is not provided to the peripheral (the peripheral is disabled)
1 = Clocks are enabled
0 = The clock is not provided to the peripheral (the peripheral is disabled)
1 = Clocks are enabled
0 = The clock is not provided to the peripheral (the peripheral is disabled)
1 = Clocks are enabled
