ware control. Input/output mode is specified by the corresponding bit in the port P1 input/output control register
(P1CR). Port P1 is configured as an input if its corresponding P1CR bit is cleared to “0”, and as an output if its cor-
responding P1CR bit is set to “1”.
ized to “0”.
used as an input port, an external interrupt input or a timer/counter input, the corresponding bit of P1CR is
cleared to “0”.
hand the corresponding output latch should be set to “1”. Data can be written into the output latch regardless of
P1CR contents, therefore initial output data should be written into the output latch before setting P1CR.

Port P1 (P15 to P10)
Port P1 is an 6-bit input/output port which can be configured as an input or an output in one-bit unit under soft-
During reset, the P1CR is initialized to “0” and port P1 is input mode. The P1 output latches are also initial-
Port P1 is also used as an external interrupt input, a timer/counter input/output, and a divider output. When
When used as a timer/counter output or divider output, the corresponding bit of P1CR is set to “1” and before-
Note 1: Bit 7 and 6 in P1DR and P1CR are always read as undefined value.
Note 2: Please set the bit 7 and 6 of P1CR to “1” in an emulator.
Note 3: Ports set to the input mode read the pin states. Ports set to the output mode read the output latch. When input pin
and output pin exist in port P1 together, the contents of the output latch which is specified as an input mode may be re-
written by executing the bit manipulation instructions.
