AT89/83EB5114
As shown on Figure 22., the PWMU1 can configure P3.5 to be used as
•
•
•
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.
Figure 22. PWMU1 Output Selector
PWMU1 can generate an interrupt. The W1IC register enables or disables interrupt and
interrupt flags (See Table 41).
