Notes 1. Pull this pin up externally.
2. The NMI pin alternately functions as the P02 pin. It functions as the P02 pin after reset. To enable the NMI pin,
set the PMC0.PMC02 bit to 1. The initial setting of the NMI pin is “No edge detected”. Select the NMI pin valid
edge using INTF0 and INTR0 registers.
