Input Input only Input XT1
P10 to P17 Input/ Port 1. Input ANI0 to ANI7
output 8-bit input/output port.
Input/output mode can be specified bit-wise.
If used as input port, an on-chip pull-up resistor can be used by
software

.
P20 Input/ Port 2. Input SI1
P21 output 8-bit input/output port. SO1
P22 Input/output mode can be specified bit-wise. SCK1
P23 If used as an input port, an on-chip pull-up resistor can be used by STB
P24 software. BUSY
P25 SI0/SB0
P26 SO0/SB1
P27 SCK0
Notes 1. When the P07/XT1 pin is used as an input port, set the bit 6 (FRC) of the processor clock control register
(PCC) to 1 (do not use the feedback resistor internal to the subsystem clock oscillator).
2. When using pins P10/ANI0 to P17/ANI7 as analog input for the A/D converter, set port 1 to the input
mode. The on-chip pull-up resistor will be automatically disabled.
