I/O PORTS

4.1.3 ARTimer alternate functions
When the PWMOE bit of ARMC register is low, the
PA2/ARTIMout pin is configured as any standard
pin of port B through the port registers.
PA2/ARTIMout pin must be configured as output
push-pull through the DDR and OR registers to be
used as PWM output. When the PWMOE bit is set,
PA2/ARTIMout becomes the PWM output.
ARTIMin/PA3 is connected through the port regis-
ters as any standard pin of port B. To use PAR-
TIMin/PA3 as AR Timer input, it must be configured
as input through DDRB.
4.1.4 UART alternate functions
PD4/RXD1 pin must be configured as input
through the DDR and OR registers to be used as
reception line for the UART. All input modes are
available and PD4 can be read independently of
the UART at any time.
PD5/TXD1 pin must be configured as output
through the DDR and OR registers to be used as
transmission line for the UART. Value present on
the pin in output mode is the Data register content
as long as no transmission is active.
