P7DR is an 8-bit register containing output data for pins P7
ups. When the CPU reads P7DR, for output pins (P7DDR = 1) it reads the value in the P7DR latch,
but for input pins (P7DDR = 0), it obtains the logic level directly from the pin, bypassing the P7DR
latch. This also applies to pins used for control signal input or output.
MOS Pull-Ups: Are available for input pins, including pins used for input of the IS and WAIT
signals. Software can turn the MOS pull-up on by writing a 1 in P7DR, and turn it off by writing a
0. The pull-ups are automatically turned off for output pins.

In mode 3 (single-chip mode), these pins can be used for general-purpose input or output or for
output of the OS and BUSY parallel handshake signals, depending on the OSE and BSE bits in the
handshake control/status register. See section 6, Parallel Handshaking Interface, for further
information. Pins used for parallel handshaking output are unaffected by the values in P7DDR and
P7DR, and their MOS pull-ups are automatically turned off.
