Function 2: Instruction queue tracking signals. Function 3: The state of the MODA and MODB pins during reset determine the initial operating mode of the MCU PE5 IPIPE0 MODA PE4 ECLK Function 1: Port E general purpose input or output pin. Function 2: Internal bus clock output that can be used as a tim- ing reference. PE3 FP21 LSTRB TAGLO Function 1: Port E general purpose input or output pin. Function 2: LCD frontplane segment driver output pin. Function 3: In MCU expanded modes of operation, LSTRB is used for the low-byte strobe function to indicate the type of bus access. Function 4: When instruction tagging is on, TAGLO is used to tag the low half of the instruction word being read into the instruction queue. PE2 FP20 R/W Function 1: Port E general purpose input or output pin. Function 2: LCD frontplane segment driver output pin. Function 3: In MCU expanded modes of operations, performs the read/write output signal for the external bus. This pin indicates direction of data on the external bus. PE1 IRQ Function 1: Port E general purpose input pin. Function 2: Maskable interrupt request input provides a means of applying asynchronous interrupt requests. Will wake up the MCU from STOP or WAIT mode PE0 XIRQ Function 1: Port E general purpose input pin. Function 2: Nonmaskable interrupt request input provides a means of applying asynchronous interrupt requests. Will wake up the MCU from STOP or WAIT mode. PH[7:0] KWH[7:0] Function 1: Port H general purpose input or output pins. Function 2: Key wake-up input pins that can generate an interrupt causing the MCU to exit STOP or WAIT mode. PJ[3:0] KWJ[3:0] Function 1: Port J general purpose input or output pins. Function 2: Key wake-up input pins that can generate an interrupt causing the MCU to exit STOP or WAIT mode. PK7 FP23 ECS ROMCTL Function 1: Port K general purpose input or output pin. Function 2: LCD frontplane segment driver output pin. Function 3: During MCU expanded modes of operation, this pin is used to enable the Flash EEPROM memory in the memory map. Function 4: During MCU expanded modes of operation, this pin is used as the emulation chip select signal. PK[3:0] BP[3:0] XADDR[17:14] Function 1: Port K general purpose input or output pins. Function 2: LCD backplane segment driver output pins. Function 3: In MCU expanded modes of operation, expanded address pins for the external bus. PL[7:4] FP[31:28] AN[15:12] Function 1: Port L general purpose input or output pins. Function 2: LCD frontplane segment driver output pins. Function 3: Analog inputs (ATD).
