Table 20.8 Pin Descriptions (Flash Memory Standard Serial I/O Mode)
NOTES:
___________
1. When using standard serial I/O mode 1, to input “H” to the TxD pin is necessary while the RESET pin is held “L”.
Therefore, connect this pin to V
CC via a resistor. Adjust the pull-up resistor value on a system not to affect a data
transfer after reset, because this pin changes to a data-output pin
2. Set the following, either or both.
_____
-Connect the CE pin to VCC.
_____
-Connect the RP pin to VSS and P16 pin to VCC.
