Signal Function Description

ERTEC 200 Pin Description
The ERTEC 200 Ethernet communication block is available in a 304-pin FBGA package. The signal names of the
ERTEC 200 are described in this section.
1.5.1

GPIO 0 to 31 and Alternative Functions

Various signals are multiplexed on the same pin. These multiplexed signals can contain up to four different functions.
The alternative functions are assigned in GPIO registers GPIO_PORT_MODE_L and GPIO_PORT_MODE_H (see
Section 4.2.2). The table describes all signals with their different functions and associated pin numbers.
