RT600

Dual-core microcontroller with 32-bit Cortex-M33 and Xtensa HiFi4

Audio DSP CPUs

10.15 General Purpose I/O (GPIO)

The RT600 provides GPIO ports with a total of up to 147 GPIO pins.

Device pins that are not connected to a specific peripheral function are controlled by the

GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate

registers allow setting or clearing any number of outputs simultaneously. The current level

of a port pin can be read back no matter what peripheral is selected for that pin.

10.15.1 Features

• Accelerated GPIO functions:

– GPIO registers are located on the AHB so that the fastest possible I/O timing can

be achieved.

– Mask registers allow treating sets of port bits as a group, leaving other bits

unchanged.

– All GPIO registers are byte and half-word addressable.

– Entire port value can be written in one instruction.

• Bit-level set and clear registers allow a single instruction set or clear of any number of

bits in one port.

• Direction control of individual bits.

• All GPIO default to high impedance after reset.

• All GPIO pins can be selected to create an edge or level-sensitive GPIO interrupt

request.

• One GPIO group interrupt can be triggered by a combination of any pin or pins.

10.16 Pin interrupt/pattern engine

The pin interrupt block configures up to eight pins from all digital pins for providing eight

external interrupts connected to the NVIC. The pattern match engine can be used in

conjunction with software to create complex state machines based on pin inputs. Any

digital pin, independent of the function selected through the switch matrix can be

configured through the SYSCON block as an input to the pin interrupt or pattern match

engine. The registers that control the pin interrupt or pattern match engine are located on

the I/O+ bus for fast single-cycle access.
