Pin Name I/O
Function
State when reset
SO1 IN/OUT • 4-bit input port (shared with serial interface)
• Input mode
SO2 IN/OUT SO1:Serial input pin
• Pull-up or pull-down
SO3 IN/OUT SO2:Serial output pin
resistance : ON (OFF
SO4 IN/OUT SO3:Serial clock pin
after reset release)
• parallel serial transfer possible
• 4-bit parallel mode
• SO4 pin is in HALT mode when the serial function is not used
• Output Latch data :HIGH
and can be applied as a release source or an interrupt source.
• Pull-up or pull-down (controlled by program for each port) is
imbedded.
• Output format can be controlled for each port by program
(CMOS/Nch)
• “Level-hold function” that prevent floating is available
