This is the input pin that specifies the operation mode. Fix this pin to low level so that its level does
not change during operation.
The internal circuit samples the status of the FLMD0 pin at the rising edge of the RESET pin.
In the normal operation mode, connect this pin to V
RESET is a signal that is input asynchronously and has a low level width regardless of the status
of the operating clock. When this signal is input, system reset is executed with higher priority than
all other operations.
In addition to being used for ordinary initializations/start operations, this signal can also be used to
cancel a standby mode (STOP).
These pins are used to connect the resonator that generates the system clock.
This is the ground pin for the A/D converter and alternate ports.
This is the reference voltage supply pin for the A/D converter.
This is the positive power supply pin. Connect all the V
This is a ground pin. Connect all the V
This is a control pin for the flash memory programming mode when connected to the dedicated
flash programming tool. Always input a low signal to this pin during flash programming.
This is the positive power supply pin for I/O.
This is the ground pin for the for I/O.
