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.
