NOTES:
1. Available in only the 128-pin version.
2. 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".
3. 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.

Apply the Flash Program, Erase Voltage to VCC1 pin
and VCC2 to the VCC2 pin. The VCC apply condition is
that VCC2 ≤ VCC1. Apply 0 V to VSS pin.
VCC1 Connect to VCC1 pin.
VCC1 Reset input pin. While RESET pin is "L" level, input a 20
cycle or longer clock to XIN pin.
VCC1 Connect a ceramic resonator or crystal oscillator
between XIN and XOUT pins. To input an externally
VCC1
generated clock, input it to XIN pin and open XOUT pin.
VCC1 Connect this pin to VCC1 or VSS.
Connect AVSS to VSS and AVCC to VCC1,
respectively.
Enter the reference voltage for A/D from this pin.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" level signal.
VCC2 Input "L" level signal.
VCC1 Input "H" or "L" level signal or open.
VCC1 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.
VCC1 Standard serial I/O mode 1: Serial clock input pin
Standard serial I/O mode 2: Input "L".
VCC1 Serial data input pin.
VCC1 Serial data output pin.
VCC1 Input "H" or "L" level signal or open.
VCC1 Input "H" or "L" level signal or open.
VCC1 Input "L" level signal.
VCC1 Connect this pin to VCC1.
VCC1 Input "H" or "L" level signal or open.
VCC1 Input "H" or "L" level signal or open.
VCC1 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC2 Input "H" or "L" level signal or open.
VCC1 Input "H" or "L" level signal or open.
