Table 4-1. LCD Module Pin Out
The LCD module gets its reset from NRST. As explained previously, this NRST is shared with the JTAG
port and the push button BP1. The LCD chip select signal is connected to NCS2 (a dedicated jumper can
disable it, making NCS2 available for other custom usage).
The SAM3U4E communicates with the LCD through PIOB where a 16-bit parallel “8080-like” protocol
data bus has to be implemented by software.
