9 / 58 page Semiconductor Group 9 1997-10-01 C515A P1.0 - P1.7 31-24 31 30 29 28 27 26 25 24 I/O Port 1 is an 8-bit quasi-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 (I IL, 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: P1.0 / INT3 / CC0 Interrupt 3 input / compare 0 output / capture 0 input P1.1 / INT4 / CC1 Interrupt 4 input / compare 1 output / capture 1 input P1.2 / INT5 / CC2 Interrupt 5 input / compare 2 output / capture 2 input P1.3 / INT6 / CC3 Interrupt 6 input / compare 3 output / capture 3 input P1.4 / INT2 Interrupt 2 input P1.5 / T2EX Timer 2 external reload / trigger input P1.6 / CLKOUT System clock output P1.7 / T2 Counter 2 input VCC 32, 33 – Supply Voltage during normal, idle, and power down mode.
