3.2.6.6.3 GPIO Distribution
The SAMA7G54-EK features one QuickSwitch 2:1 multiplexer to distribute the MPU PIOs.
The multiplexer distributes the PIOs according to the J3 status:
- J3 is open (default mode): the Ethernet 10/100 interface is distributed.
 - J3 is closed: the PDMC0 interface is distributed.
 
| PIO | MPU Net Name | Device Net Name | Function | 
|---|---|---|---|
| PD22 | PD22 | ETH1_TX0_PD22 | Transmit data line 0 | 
| PDMC0_CLK_PD22 | PDM clock line | ||
| PD23 | PD23 | ETH1_TX1_PD23 | Transmit data line 1 | 
| PDMC0_DS0_PD23 | PDM data line 0 | ||
| PD24 | PD24 | ETH1_CRSDV_PD24 | Receive data valid or carrier sense and data valid | 
| PDMC0_DS1_PD24 | PDM data line 1 |
