10 / 26 page MAXQ618 16-Bit Microcontroller with Infrared Module 10 Pin Description (continued) PIN NAME FUNCTION BARE DIE TQFN-EP Port 1 General-Purpose, Digital I/O Pins with Interrupt Capability. These port pins function as general-purpose I/O pins with their input and output states controlled by the PD1, PO1, and PI1 registers. All port pins default to high-impedance mode after a reset. Software must configure these pins after release from reset to remove the high- impedance condition. All external interrupts must be enabled from software before they can be used. GPIO PORT PIN EXTERNAL INTERRUPT 33 33 P1.0/INT0 P1.0 INT0 35 34 P1.1/INT1 P1.1 INT1 36 35 P1.2/INT2 P1.2 INT2 38 36 P1.3/INT3 P1.3 INT3 39 37 P1.4/INT4 P1.4 INT4 40 38 P1.5/INT5 P1.5 INT5 41 39 P1.6/INT6 P1.6 INT6 42 40 P1.7/INT7 P1.7 INT7 Port 2 General-Purpose, Digital I/O Pins. These port pins function as general-purpose I/O pins with their input and output states controlled by the PD2, PO2, and PI2 registers. All port pins default to high-impedance mode after a reset. Software must configure these pins after release from reset to remove the high-impedance condition. All special functions must be enabled from software before they can be used.

These port pins function as general-purpose I/O pins with their input and output states controlled by the PD3, PO3, and PI3 registers. All port pins default to high-impedance mode after a reset. Software must configure these pins after release from reset to remove the high- impedance condition. All external interrupts must be enabled from software before they can be used.
