TECHNICAL DATA

6.7 Port G
Port G pins reset to high-impedance inputs except in expanded modes where reset
causes PG7 to become the CSPROG output. Alternate functions for port G bits [7:4]
are chip select outputs. All port G bits are bidirectional and have corresponding data
direction bits.
The GWOM control bit in the OPT2 register disables port G's P-channel output drivers.
Because the N-channel driver is not affected by GWOM, setting GWOM causes port
G to become an open-drain-type output port suitable for wired-OR operation. In wired-
OR mode, (PORTG bits are at logic level zero), pins are actively driven low by the N-
channel driver. When a port G bit is at logic level one, the associated pin is in a high-
impedance state, as neither the N-channel nor the P-channel devices are active. It is
customary to have an external pull-up resistor on lines that are driven by open-drain
devices. Port G can be configured for wired-OR operation in any operating mode.
DDG[7:0] — Data Direction for Port G
0 = Input
1 = Output
6.8 System Configuration Options 2
The system configuration options 2 register controls several configuration parameters.
Bit 6, CWOM, is the only bit in this register that directly affects parallel I/O.
