T4. The input level can be switched between CMOS compatible input level and TTL level by the P7 input level selection bit of the port
control register 2 (address 002F16).
T5. The input level can be switched between CMOS compatible input level and TTL level by the P7 input level selection bit of the port
control register 2 (address 002F16).
The port P8 direction register and port P7 input register can be switched by the P8 function selection bit of the port control register 2
(address 002F16).
