T1. The input level can be switched between CMOS compatible input level and TTL level by the P4 input level selection bit of the port control
register 2 (address 002F16).
T2. The input level can be switched between CMOS compatible input level and TTL level by the P4 input level selection bit of the port control
register 2 (address 002F16).
The port P8 and port P4 input register can be switched by the P8 function selection bit of the port control register 2 (address 002F16).
T3. The input level can be switched between CMOS compatible input level and TTL level by the input level selection bit of the data bus buffer
control register (address 002A16).
