Port 1 Register (PORT1)
Note: * Determined by state of pins P17 to P10.
PORT1 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port 1 pins (P17 to P10) must always be performed on P1DR.
If a port 1 read is performed while P1DDR bits are set to 1, the P1DR values are read. If a port 1
read is performed while P1DDR bits are cleared to 0, the pin states are read.
After a reset and in hardware standby mode, PORT1 contents are determined by the pin states, as
P1DDR and P1DR are initialized. PORT1 retains its prior state in software standby mode.
9.2.3
Port 1 pins also function as PPG output pins (PO15 to PO8), TPU I/O pins (TCLKA, TCLKB,
TCLKC, TCLKD, TIOCA0, TIOCB0, TIOCC0, TIOCD0, TIOCA1, TIOCB1, TIOCA2, and
TIOCB2), external interrupt input pins (IRQ0 and IRQ1), and address bus output pins (A23 to
A20). Port 1 pin functions are shown in table 9-3.
Note: The PPG output is not implemented in the H8S/2635 Group.
