Notes 1. Mask ROM versions only
2. IEBus controller versions only
3. CAN controller versions only
4. Flash memory versions only
5. Pull this pin up externally.
6. I
2C bus versions (Y products) only
7. 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.
Remark
GF: 100-pin plastic QFP (14
