3. I/O Pin Usage
3.1 KSO0~7
These pins are direct output from the 8051’s Port1 and dedicated for key scan output. The pin’s input
function is removed. Read 8051’s Port1 is only read the data in the Port1’s output register. These pins are
“Pseudo open-drain” structure.
3.2 KSO8~15
These pins are direct output from the 8051’s Port2 and dedicated for key scan output. The pin’s input
function is removed. Read 8051’s Port2 is only read the data in the Port2’s output register. These pins are
“Pseudo open-drain” structure.
3.3 KSO16~17, GPIO0~1
These pins are output from MTP805’s XFR. They can be used as key scan output or general purpose I/O.
Read these pins will read the data on pin. These pins are also “Pseudo open-drain” structure.
3.4 MSCLK, MSDATA
These pins are connected to 8051’s P3.1 and P3.0. The usage of these pins are the same as standard 8051
except the UART’s function being not provided. These pins are also “Pseudo open-drain” structure.
