1.5 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
