PWM/Timers Alternate Functions
The pins of Port A and C can be configured to be I/
O of the three PWM/Timers available on the
ST52T410/ST52x420. The configuration of these
pins is performed by using the Configuration
Registers REG_CONF 12 and REG_CONF 16 if
the related pin has to be output. When the related
pin has to be used as an input peripheral the
configuration is performed by the relative
peripheral configuration registers (See PWM/
Timer Session).
Warning:
in order to use PC1, PC2 and PC3
pins as standard I/O pins, the PWM/Timers
must be configured in Timer mode
