Notes:
1. A number that is not enclosed in parentheses in the “Number of pins” column indicates the main pins, while a
number enclosed in parentheses indicates multipurpose pins.
2. After the reset condition is released, maintain the NMIRQ pin at the high level until the initialization routine
(which sets the stack pointer SP) is completed. If the NMIRQ pin is not used, connect it to VDD via a resistor.
