I/O PORTS
[Direction Registers] PiD
The 38B7 group has 75 programmable I/O pins arranged in ten in-
dividual I/O ports (P1, P3, P4, P5, P6, P7, P8, P9, PA and PB).
The I/O ports have direction registers which determine the input/
output direction of each individual pin. Each bit in a direction reg-
ister corresponds to one pin, and each pin can be set to be input
port or output port. When “0” is written to the bit corresponding to
a pin, that pin becomes an input pin. When “1” is written to that
pin, that pin becomes an output pin. If data is read from a pin set
to output, the value of the port output latch is read, not the value of
the pin itself. Pins set to input (the bit corresponding to that pin
must be set to “0”) are floating and the value of that pin can be
read. If a pin set to input is written to, only the port output latch is
written to and the pin remains floating.

[High-Breakdown-Voltage Output Ports]
The 38B7 group has seven ports with high-breakdown-voltage
pins (ports P0 to P5 and P60–P63). The high-breakdown-voltage
ports have P-channel open-drain output with Vcc – 45 V of break-
down voltage. Each pin in ports P0 to P3 has an internal pull-down
resistor connected to VEE. At reset, the P-channel output transis-
tor of each port latch is turned off, so that it goes to VEE level (“L”)
by the pull-down resistor.
Writing “1” (weak drivability) to bit 7 of the FLDC mode register
(address 0EF416) shows the rising transition of the output transis-
tors for reducing transient noise. At reset, bit 7 of the FLDC mode
register is set to “0” (strong drivability).
[Pull-up Control Register] PULL
Ports P64–P67, P7, P80–P83, P9, PA and PB have built-in pro-
grammable pull-up resistors. The pull-up resistors are valid only in
the case that the each control bit is set to “1” and the correspond-
ing port direction registers are set to input mode.
