I/O PORTS (Cont’d)

4.1.3 SPI alternate functions

PA6/Sin and PA5/Scl pins must be configured as

input through the DDR and OR registers to be

used as data in and data clock (Slave mode) for

the SPI. All input modes are available and I/O's

can be read independently of the SPI at any time.

PA7/Sout must be configured in open drain output

mode to be used as data out for the SPI. In output

mode, the value present on the pin is the port data

output, while serial transmission is possible only in

open drain mode.

4.1.4 UART alternate functions

PB0/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 PB0 can be read independently of

the UART at any time.

PB1/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.
