and one word select signal. The basic I
always the master, and one slave. The I
receive channel, each of which can operate as either a master or a slave.
The LPC17xx include four 32-bit timer/counters. The timer/counter is designed to count
cycles of the system derived clock or an externally-supplied clock. It can optionally
generate interrupts, generate timed DMA requests, or perform other actions at specified
timer values, based on four match registers. Each timer/counter also includes two capture
inputs to trap the timer value when an input signal transitions, optionally generating an
interrupt.

S-bus serial I/O controllers
The interface has separate input/output channels each of which can operate in master
or slave mode.
Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
Mono and stereo audio data supported.
The sampling frequency can range from 16 kHz to 96 kHz (16, 22.05, 32, 44.1, 48,
96) kHz.
Support for an audio master clock.
Configurable word select period in master mode (separately for I
output).
Two 8-word FIFO data buffers are provided, one for transmit and one for receive.
Generates interrupt requests when buffer levels cross a programmable boundary.
Two DMA requests, controlled by programmable buffer levels. These are connected
to the GPDMA block.
Controls include reset, stop and mute options separately for I
output.
A 32-bit timer/counter with a programmable 32-bit prescaler.
Counter or timer operation.
Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
