9 / 57 page SAB 80C515A/83C515A-5 Semiconductor Group 8 P1.7 - P1.0 29-36 24-31 I/O Port 1 is an 8-bit bidirectional I/O port with internal pullup resistors. Port 1 pins that have 1's written to them are pulled high by the internal pullup resistors, and in that state can be used as inputs. As inputs, port 1 pins being externally pulled low will source current (IIL in the DC characteristics) because of the internal pullup resistors. The port is used for the low- order address byte during program verification. Port 1 also contains the interrupt, timer, clock, capture and compare pins that are used by various options. The output latch corresponding to a secondary function must be programmed to a one (1) for that function to operate (except when used for the compare functions). The secondary functions are assigned to the port 1 pins as follows: – INT3/CC0 (P1.0): interrupt 3 input / compare 0 output / capture 0 input – INT4/CC1 (P1.1): interrupt 4 input / compare 1 output / capture 1 input – INT5/CC2 (P1.2): interrupt 5 input / compare 2 output / capture 2 input – INT6/CC3 (P1.3): interrupt 6 input / compare 3 output / capture 3 input – INT2(P1.4): interrupt 2 input – T2EX (P1.5): timer 2 external reloadtrigger input – CLKOUT (P1.6): system clock output – T2 (P1.7): counter 2 input XTAL2 39 36 – XTAL2 Input to the inverting oscillator amplifier and input to the internal clock generator circuits.
