It is bit-wise programmable for input or output via direction bits. For a pin configured as input, the output driver is put into high-impedance state. PORT1 is used as the 16-bit address bus (A) in demultiplexed bus modes and also after switching from a demultiplexed bus mode to a multiplexed bus mode. The following PORT1 pins also serve for alt. functions: CC60 CAPCOM6: Input / Output of Channel 0 COUT60 CAPCOM6: Output of Channel 0 CC61 CAPCOM6: Input / Output of Channel 1 COUT61 CAPCOM6: Output of Channel 1 CC62 CAPCOM6: Input / Output of Channel 2 COUT62 CAPCOM6: Output of Channel 2 COUT63 Output of 10-bit Compare Channel CTRAP CAPCOM6: Trap Input CTRAP is an input pin with an internal pullup resistor. A low level on this pin switches the compare outputs of the CAPCOM6 unit to the logic level defined by software. CC6POS0 CAPCOM6: Position 0 Input, **) EX0IN Fast External Interrupt 0 Input CC6POS1 CAPCOM6: Position 1 Input, **) EX1IN Fast External Interrupt 1 Input CC6POS2 CAPCOM6: Position 2 Input, **) EX2IN Fast External Interrupt 2 Input EX3IN Fast External Interrupt 3 Input, T7IN CAPCOM2: Timer T7 Count Input CC24IO CAPCOM2: CC24 Capture Inp./Compare Outp. CC25IO CAPCOM2: CC25 Capture Inp./Compare Outp. CC26IO CAPCOM2: CC26 Capture Inp./Compare Outp. CC27IO CAPCOM2: CC27 Capture Inp./Compare Outp. Note: The marked (**) input signals are available only in devices with a full function CAPCOM6. Table 2 Pin Definitions and Functions (cont’d) Symbol Pin No. Input Outp. Function |
