I/O PORTS (cont’d)
10.7 DEVICE-SPECIFIC I/O PORT CONFIGURATION
The I/O port register configurations are summa-
rized as follows:
Standard Ports
PA7:0, PB6:0
PC1:0 (multiplexed with OSC1,OSC2)
The selection between OSC1 or PC0 and OSC2 or
PC1 is done by the option byte (refer to
15.1 on page
able on PC1:0.
Port C is not present on ROM devices.
Note: PCOR not implemented but p-transistor al-
ways active in output mode (refer to
page
Table 10. Port Configuration (Standard Ports)
Note: On ports where the external interrupt capability is selected using the EISR register, the configuration is as follows:
