LPC2361/62
Single-chip 16-bit/32-bit MCU
7.18.1 Features
• 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 48 kHz (16 kHz, 22.05 kHz,
32 kHz, 44.1 kHz or 48 kHz).
• Configurable word select period in master mode (separately for I
2
S input and 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
2
S input and I
2
S output.
7.19 General purpose 32-bit timers/external event counters
The LPC2361/2362 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 or perform other actions at specified timer values, based on four
match registers. The Timer/Counter also includes two capture inputs to trap the timer
value when an input signal transitions, optionally generating an interrupt.
7.19.1 Features
• 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.
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
