9.4.3
PORT7 shows the pin states. This register cannot be modified.
Note: * Determined by the states of pins P77 to P70.
9.4.4
Port 7 pins also function as the 8-bit timer I/O pins (TMRI01, TMCI01, TMRI23 * , TMCI23 * ,
TMO0, TMO1, TMO2 * , and TMO3 * ) and SCI I/O pins (SCK2, RxD2 and TxD2). Port 7 pin
functions are shown below.
Note: * Supported only by the H8S/2268 Group.

Description
If a port 1 read is performed while P7DDR bits are set to
1, the P7DR values are read. If a port 1 read is performed
while P7DDR bits are cleared to 0, the pin states are
read.
