BLE_WAKEUP_REQ
If '1', the BLE wakes up. Must be kept high at least for 1 low
power clock period.
0x0
If the BLE is in deep sleep state, then by setting this bit it will
cause the wakeup LP IRQ to be asserted with a delay of 3 to
4 low power cycles.

PWM_MODE
0 = PWM signals are '1' during high time.
0x0
1 = PWM signals send out the (fast) clock divided by 2 dur-
ing high time. So it will be in the range of 1 to 8 MHz.
