PWMU1 Output Selector
As shown on Figure 22., the PWMU1 can configure P3.5 to be used as
The PWMU1 module 0 output (W1R = 1 and W1EN0 = 1)
The External Clocking output (W1OCLK = 1 and W1EN0 = 1)
An I/O port (W1EN0 = 0)
This configuration is made via W1CON register (See Table 34.). By default, W1CON
register contains 00h. So P3.5 is configured as an I/O port.
The W1INV0 bit allows to start PWMU1 module 0 period with a high (if set) or low level.

PWMU1 Interrupt System
PWMU1 can generate an interrupt. The W1IC register enables or disables interrupt and
interrupt flags (See Table 41).
