2 / 10 page 2 1.0 SIGNAL DESCRIPTION Port 0 (P0.0 - P0.7): Port 0 is an 8-bit input only port when used in its default mode. When configured for their alternate function, five of the bits are bi-directional EDAC check bits as shown in Table 1. Port 1 (P1.0 - P1.7): Port 1 is an 8-bit, quasi-bidirectional, I/O port. All pins are quasi-bidirectional unless the alternate function is selected per Table 2. When the pins are configured for their alternate functions, they act as standard I/O, not quasi- bidirectional. Port 2 (P2.0 - P2.7):Port 2 is an 8-bit, multifunctional, I/O port. These pins are shared with timer 2 functions, serial data I/O and PWM0 output, per Table 3. AD0-AD7: The lower 8-bits of the multiplexed address/data bus. The pins on this port are bidirectional during the data phase of the bus cycle. AD8-AD15: The upper 8-bits of the multiplexed address/data bus. The pins on this port are bidirectional during the data phase of the 16-bit bus cycle. When running in 8-bit bus width, these pins are non-multiplexed, dedicated upper address bit outputs. HSI: Inputs to the High Speed Input Unit. Four HSI pins are available: HSI.0, HSI.1, HSI.2, and HSI.3. Two of these pins (HSI.2 and HSI.3) are shared with the HSO Unit. Two of these pins (HSI.0 and HSI.1) have alternate functions for Timer 2. HSO: Outputs from the High Speed Output Unit. Six HSO pins are available: HSO.0, HSO.1, HSO.2, HSO.3, HSO.4, and HSO.5. Pins HSO.4 and HSO.5 are shared with pins HSI.2 and HSI.3 of the HSI Unit respectively. Table 1. Port 0 Alternate Functions Port Pin Alternate Name Alternate Function P0.0-P0.3, P0.6 ECB0-ECB4 Error Detection & Correction Check Bits P0.4 P0.5 Input Port Pins P0.7 EXTINT Setting IOC1.1=1 will allow P0.7 to be used for EXTINT (INT07) Table 2. Port 1 Alternate Functions Port Pin Alternate Name Alternate Function P1.0 P1.0 I/O Pin P1.1 P1.1 I/O Pin P1.2 P1.2 I/O Pin P1.3 PWM1 Setting IOC3.2=1 enables P1.3 as the Pulse Width Modulator (PWM1) output pin. P1.4 PWM2 Setting IOC3.3=1 enables P1.4 as the Pulse Width Modulator (PWM2) output pin. P1.5 BREQ Bus Request, output activated when the bus controller has a pending external memory cycle. P1.6 HLDA Bus Hold Acknowledge, output indicating the release of the bus. P1.7 HOLD Bus Hold, input requesting control of the bus. Table 3. Port 2 Alternate Functions Port Pin Alternate Name Alternate Function P2.0 TXD Transmit Serial Data. P2.1 RXD Receive Serial Data. P2.2 EXTINT External interrupt. Clearing IOC1.1 will allow P2.2 to be used for EXTINT (INT07) P2.3 T2CLK Timer 2 clock input and Serial port baud rate generator input. P2.4 T2RST Timer 2 Reset P2.5 PWM0 Pulse Width Modulator output 0 P2.6 T2UP-DN Controls the direction of the Timer 2 counter. Logic High equals count down. Logic low equals count up. P2.7 T2CAPTURE A rising edge on P2.7 causes the value of Timer 2 to be captured into this register, and generates a Timer 2 Capture interrupt (INT11). |
