8 / 85 page Semiconductor Group 8 1997-12-01 C505 / C505C C505A / C505CA Table 3 Pin Definitions and Functions Symbol Pin Number I/O *) Function P1.0-P1.7 40-44,1-3 40 41 42 43 44 1 2 3 I/O Port 1 is an 8-bit quasi-bidirectional port with internal pull-up ar- rangement. Port 1 pins can be used for digital input/output or as analog inputs of the A/D converter. Port 1 pins that have 1’s written to them are pulled high by internal pull-up transistors and in that state can be used as inputs. As in- puts, port 1 pins being externally pulled low will source cur- rent ( IIL, in the DC characteristics) because of the internal pullup transistors. Port 1 pins are assigned to be used as analog inputs via the register P1ANA. As secondary digital functions, port 1 contains the interrupt, timer, clock, capture and compare pins. The output latch corresponding to a secondary function must be pro- grammed to a one (1) for that function to operate (except for compare functions). The secondary functions are assigned to the pins of port 1 as follows: P1.0 / AN0 / INT3 / CC0 Analog input channel 0 interrupt 3 input / capture/compare channel 0 I/O P1.1 / AN1 / INT4 / CC1 Analog input channel 1/ interrupt 4 input / capture/compare channel 1 I/O P1.2 / AN2 / INT5 / CC2 Analog input channel 2 / interrupt 5 input / capture/compare channel 2 I/O P1.3 / AN3 / INT6 / CC3 Analog input channel 3 interrupt 6 input / capture/compare channel 4 I/O P1.4 / AN4 Analog input channel 4 P1.5 / AN5 / T2EX Analog input channel 5 / Timer 2 external reload / trigger input P1.6 / AN6 / CLKOUT Analog input channel 6 / system clock output P1.7 / AN7 / T2 Analog input channel 7 / counter 2 input Port 1 is used for the low-order address byte during program verification of the C505-2R and C505C-2R. *) I = Input O = Output |
