I/O PORTS (Cont’d)
4.1.3 ARTimer alternate functions
When bit PWMOE of register ARMC is low, pin AR-
TIMout/PA2 is configured as any standard pin of
port B through the port registers. When PWMOE is
high, ARTIMout/PA2 is the PWM output, independ-
ently of the port registers configuration. ARTIMin/
PA3 is connected through the port registers as any
standard pin of port B. To use PARTIMin/PA3 as
AR Timer input, it must be configured as input
though 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.
