Description
PWMU1 update bit
Set by software to request the load of all shadow registers on the next
overtaking of the W1C counter. Reset by hardware after the loading of the
shadow registers
PWMU1 Run control bit
Set by software to turn the PWMU1 counter on. Must be cleared by software to
turn the PWMU1 counter off.
Not used
Output Clocking Control bit.
This bit allows to choose between the output clocking signal and the PWM1M0
output.
If set, the external clocking is chosen, if clear, PWM1M0 is chosen.

10 Timer 1 Overflow
11 External clock input on W1CI at max rate = f
PWMU1 Module 0 inverter bit
Select the output PWM mode. If set, PWM module 0 output starts with high
level.
PWMU1 Module 0 enable bit
Enable PWMU1 module 0 if set. If clear, P3.5 is an I/O port.
W1F13
Description
PWMU1 high bits counter control frequency
The PWMU1 counter is counting from zero up to W1F15-0 value.
