Table 17.9.1. Pin Functions (Flash Memory Standard Serial I/O Mode)
NOTES:
1. When using standard serial input/output mode 1, to input “H” to the TxD pin is necessary while the
___________
RESET pin is “L”. Therefore, connect this pin to VCC 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 following either or both
_____
Connect the CE pin to VCC.
_____
Connect the RP pin to VSS and the P16 pin to VCC.
Pin
Description
VCC,VSS
Apply the voltage guaranteed for Program and Erase to Vcc pin and 0
V to Vss pin.
CNVSS
Connect to Vcc pin.
RESET
XIN
Connect a ceramic resonator or crystal oscillator between X IN and
XOUT pins. To input an externally generated clock, input it to X IN pin
and open XOUT pin.
XOUT
AVCC, AVSS
VREF
Connect AVss to Vss and AVcc to Vcc, respectively.
Enter the reference voltage for AD from this pin.
P15, P17
Input "H" or "L" level signal or open.
P60 to P63
Input "H" or "L" level signal or open.
P64
Standard serial I/O mode 1: BUSY signal output pin
Standard serial I/O mode 2: Monitor signal output pin for boot program
operation check
P65
P66
Serial data input pin
P67
Serial data output pin
P70 to P77
Input "H" or "L" level signal or open.
P80 to P84,
P87
Input "H" or "L" level signal or open.
P90 to P93,
Input "H" or "L" level signal or open.
P100 to P107
Input "H" or "L" level signal or open.
