Preliminary Specification
This is a preliminary specification and is subject to change.
30. Flash Memory
30.9.4 Standard Serial I/O Mode 1
In standard serial I/O mode 1, a serial programmer is connected to the MCU by using clock
synchronous serial I/O.
Table 30.19 lists Pin Functions (Flash Memory Standard Serial I/O Mode 1) and Table 30.20 lists
Setting of Standard Serial I/O Mode 1.
Figure 30.20 shows Circuit Application in Standard Serial I/O Mode 1. Control pins vary by programmer.
For more information, refer to the programmer manual.

Description
Apply the flash program and erase voltage to the VCC1 pin,
and VCC2 to the VCC2 pin. The VCC application condition is
that VCC2 ≤ VCC1. Apply 0 V to the VSS pin.
Connect to the VCC1 pin.
Reset input pin. During td(OCOS), input a low-level signal to
the RESET pin.
Input a high-level signal to the XIN pin and open the XOUT pin
when a main clock is not used.
Connect a ceramic resonator or crystal oscillator between pins
XIN and XOUT when the main clock is used. To input an
externally generated clock, input it to the XIN pin and open the
XOUT pin.
Connect this pin to VSS or VCC1.
Connect AVCC to VCC1 and AVSS to VSS, respectively.
Reference voltage input pin for A/D converter.
Input a high- or low-level signal or leave open.
