I/O Ports
The eight I/O pins (six on the 8-pin package option) are bi-directional (see
Figure 14
). The bi-directional I/O pins can be indi-
vidually configured by software to operate as high-impedance inputs, as inputs with weak pull-up, or as push-pull outputs. The
operating state is determined by the contents of the corresponding bits in the data and configuration registers. Each bi-direc-
tional I/O pin can be used for general purpose I/O, or in some cases, for a specific alternate function determined by the on-chip
hardware.
The high voltage FMS7401 device’s G0/T1HS1 and G5/T1HS2 output port levels can be as high as the Vdd supply voltage if
powered from the Vdd pin, (see
Figure 15
). The FMS7401L device’s G0/T1HS1 and G5/T1HS2 output port levels can be only
as high as the Vcc supply voltage since it is a low voltage device. All the other output ports for both the low and high voltage
devices are supplied by the Vcc pin (see
Figure 15
).

8.1
The I/O pins (G0–G7) have three memory mapped port registers associated with the I/O circuitry: a Port Configuration
(PORTGC), Port Data (PORTGD) and Port Input (PORTGP) register.
1
PORTGC is used to configure the pins as inputs or out-
puts. A pin may be configured as an input by writing a 0 or as an output by writing a 1 to its corresponding PORTGC bit. If a
pin is configured as an output, its PORTGD bit represents the state of the pin (1 = logic high, 0 = logic low). If the pin is con-
figured as an input, its PORTGD bit selects whether the pin is a weak pull-up or a high-impedance input.
