2.2.14 PE3 / LSTRB / TAGLO — Port E I/O Pin 3
PE3 is a general purpose input or output pin. In MCU expanded modes of operation, LSTRB can be used
for the low-byte strobe function to indicate the type of bus access and when instruction tagging is on,
TAGLO is used to tag the low half of the instruction word being read into the instruction queue.
2.2.15 PE2 / R/W—Port E I/O Pin 2
PE2 is a general purpose input or output pin. In MCU expanded modes of operations, this pin drives the
read/write output signal for the external bus. It indicates the direction of data on the external bus.
2.2.16 PE1 / IRQ — Port E Input Pin 1
PE1 is a general purpose input pin and the maskable interrupt request input that provides a means of
applying asynchronous interrupt requests. This will wake up the MCU from STOP or WAIT mode.
2.2.17 PE0 / XIRQ — Port E Input Pin 0
PE0 is a general purpose input pin and the non-maskable interrupt request input that provides a means of
applying asynchronous interrupt requests. This will wake up the MCU from STOP or WAIT mode.
