LPC4350/30/20/10

32-bit ARM Cortex-M4/M0 microcontroller

In the two-counter case, the following operational elements are global to the SCT, but the

last three can use match conditions from either counter:

• Clock selection

• Inputs

• Events

• Outputs

• Interrupts

7.16.1.1

Features

• Two 16-bit counters or one 32-bit counter.

• Counters clocked by bus clock or selected input.

• Counters can be configured as up-counters or up-down counters.

• State variable allows sequencing across multiple counter cycles.

• Event combines input or output condition and/or counter match in a specified state.

• Events control outputs and interrupts.

• Selected events can limit, halt, start, or stop a counter.

• Supports:

– up to 8 inputs

– 16 outputs

– 16 match/capture registers

– 16 events

– 32 states

7.16.2 Serial GPIO (SGPIO)

The Serial GPIOs offer standard GPIO functionality enhanced with features to accelerate

serial stream processing.

7.16.2.1

Features

• Each SGPIO input/output slice can be used to perform a serial to parallel or parallel to

serial data conversion.

• 16 SGPIO input/output slices each with a 32-bit FIFO that can shift the input value

from a pin or an output value to a pin with every cycle of a shift clock.

• Each slice is double-buffered.

• Interrupt is generated on a full FIFO, shift clock, or pattern match.

• Slices can be concatenated to increase buffer size.

• Each slice has a 32-bit pattern match filter.
