I Reset input pin. While RESET pin is “L” level, input a 20
cycle or longer clock to XIN pin.
I Connect a ceramic resonator or crystal oscillator between
O ^{XIN and XOUT pins. To input an externally generated}
clock, input it to XIN pin and open XOUT pin.
I Connect this pin to VCC1 or VSS.
Connect AVSS to VSS and AVCC to VCC1, respectively.
I Enter the reference voltage for A/D from this pin.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “H” level signal.
I Input “L” level signal.
I Input “H” or “L” level signal or open.
O Standard serial I/O mode 1: BUSY signal output pin
Standard serial I/O mode 2: Monitors the boot program
operation check signal output pin.
I Standard serial I/O mode 1: Serial clock input pin
Standard serial I/O mode 2: Input “L”.
I Serial data input pin.
O Serial data output pin. ⁽¹⁾
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
I Input “L” level signal. ⁽²⁾
I Connect this pin to VCC1.
I Input “H” or “L” level signal or open.
I Input “H” or “L” level signal or open.
NOTES:
1. When using the standard serial I/O mode, the internal pull-up is enabled for the TXD1 (P6_7) pin
while the RESET pin is “L”.
2. When using the standard serial I/O mode, the P0_0 to P0_7, P1_0 to P1_7 pins may become
indeterminate while the P8_4 pin is “H” and the RESET pin is “L”. If this causes a program, apply “L”
to the P8_4 pin.
