Description
Clock signal input for debugging. Connect this signal to the DCLK pin of the S1C17 MCU.
Ground. Connect this signal to the ground of the S1C17 MCU.
Serial communication signal input/output for debugging. Connect this signal to the DSIO
pin of the S1C17 MCU.
Debug status signal input. Connect this signal to the DST2 pin of the S1C17 MCU.
Flash memory programming voltage output. Connect this output to the V
S1C17 MCU when a flash memory programming voltage is externally supplied to the
S1C17 MCU that has a flash memory programming power supply pin (V
Ground. Connect this signal to the ground of the S1C17 MCU.
Target system reset signal output. Connect this signal to the #RESET pin of the S1C17
MCU. The TARGET_RST_OUT pin is configured as an Nch open drain output with a 10
kΩ pull-up resistor, so this signal can be input to the S1C17 MCU in a wired OR
connection even if another reset signal, such as a user reset switch signal, must be input.
Target system power supply voltage input. Use this pin when supplying the interface
power voltage from the target system.
Power supply pin. This pin always outputs 3.3 V for the target system. The maximum drive
capability is 100 mA.
