S71255-00-000 3/04 2.1 Pin Descriptions TABLE 2-1: PIN DESCRIPTIONS (1 OF 2) Symbol Type1 Name and Functions P0[7:0] I/O Port 0: Port 0 is an 8-bit open drain bi-directional I/O port. As an output port each pin can sink several LS TTL inputs. Port 0 pins float that have ‘1’s written to them, and in this state can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external memory. In this application, it uses strong internal pull- ups when transitioning to VOH. Port 0 also receives the code bytes during the external host mode programming, and outputs the code bytes during the external host mode verification. External pull-ups are required during program verification. P1[7:0] I/O with internal pull-ups Port 1: Port 1 is an 8-bit bi-directional I/O port with internal pull-ups. The Port 1 output buff- ers can drive LS TTL inputs. Port 1 pins are pulled high by the internal pull-ups when “1”s are written to them and can be used as inputs in this state. As inputs, Port 1 pins that are externally pulled low will source current because of the internal pull-ups. P1[5, 6, 7] have high current drive of 16 mA. Port 1 also receives the low-order address bytes during the external host mode programming and verification. P1[0] I/O T2: External count input to Timer/Counter 2 or Clock-out from Timer/Counter 2 P1[1] I T2EX: Timer/Counter 2 capture/reload trigger and direction control P1[2] I ECI: PCA Timer/Counter External Input: This signal is the external clock input for the PCA timer/counter. P1[3] I/O CEX0: Compare/Capture Module External I/O Each compare/capture module connects to a Port 1 pin for external I/O. When not used by the PCA, this pin can handle standard I/O. P1[4] I/O SS#: Master Input or Slave Output for SPI. OR CEX1: Compare/Capture Module External I/O P1[5] I/O MOSI: Master Output line, Slave Input line for SPI OR CEX2: Compare/Capture Module External I/O P1[6] I/O MISO: Master Input line, Slave Output line for SPI OR CEX3: Compare/Capture Module External I/O P1[7] I/O SCK: Master clock output, slave clock input line for SPI OR CEX4: Compare/Capture Module External I/O P2[7:0] I/O with internal pull-up Port 2: Port 2 is an 8-bit bi-directional I/O port with internal pull-ups. Port 2 pins are pulled high by the internal pull-ups when “1”s are written to them and can be used as inputs in this state. As inputs, Port 2 pins that are externally pulled low will source current because of the internal pull-ups. Port 2 sends the high-order address byte during fetches from external Pro- gram memory and during accesses to external Data Memory that use 16-bit address (MOVX@DPTR). In this application, it uses strong internal pull-ups when transitioning to VOH. Port 2 also receives some control signals and a partial of high-order address bits dur- ing the external host mode programming and verification. P3[7:0] I/O with internal pull-up Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 3 output buff- ers can drive LS TTL inputs. Port 3 pins are pulled high by the internal pull-ups when “1”s are written to them and can be used as inputs in this state. As inputs, Port 3 pins that are externally pulled low will source current because of the internal pull-ups. Port 3 also receives some control signals and a partial of high-order address bits during the external host mode programming and verification. P3[0] I RXD: Universal Asynchronous Receiver/Transmitter (UART) - Receive input P3[1] O TXD: UART - Transmit output P3[2] I INT0#: External Interrupt 0 Input |
