Table 1-6: UART Pin Functions

Pin Name

I/ONote

Function

Alternate FunctionNote

UART-TXD

UART transmit data output

GPIO8

UART-RXD

UART receive data input

GPIO9

UART-DCD_N

UART carrier detection signal

GPIO10

UART-DSR_N

UART data set ready signal

GPIO11

UART-CTS_N

UART transmit enable signal

GPIO12

Note: Primary

and

alternate

functions

are

selected

with

the

GPIO_PORT_MODE_H

and

GPIO_PORT_MODE_L registers. In this table the I/O types are listed for the UART function.

Table 1-7: SPI1 Pin Functions

Pin Name

I/ONote

Function

Alternate FunctionNote

SPI1_SSPRXD

SPI1 receive data input

GPIO18

SPI1_SSPTXD

SPI1 transmit data output

GPIO19

SPI1_SCLKOUT

SPI1 clock output

GPIO20

SPI1_SFRMOUT

SPI1 serial frame output signal

GPIO21

SPI1_SFRMIN

SPI1 serial frame input signal

GPIO22, DBGACK

SPI1_SCLKIN

SPI1 clock input

GPIO23

SPI1_SSPCTLOE

SPI1 clock and serial frame output enable

GPIO16

SPI1_SSPOE

SPI1 output enable

GPIO17

Note: Primary

and

alternate

functions

are

selected

with

the

GPIO_PORT_MODE_H

and

GPIO_PORT_MODE_L registers. In this table the I/O types are listed for the SPI1 function.

Table 1-8: MC_PLL Pin Functions

Pin Name

I/ONote 1

Function

Alternate FunctionNote 1

PLL_EXT_IN_N

MC_PLL input signal

GPIO24

TGEN_OUT1_N

MC_PLL output signalNote 2

GPIO25

Notes: 1. Primary and alternate functions are selected with the GPIO_PORT_MODE_H register. In this table

the I/O types are listed for the MC_PLL function.

2. For a PROFINET IRT application, GPIO25 must be configured as TGEN_OUT1_N output pin. A syn-

chronous clock signal is then output at this pin; during certification of a PROFINET IO device with

IRT support this signal must be accessible from the outside.
