Register block

Fields

tasks_start: TASKS_START

0x00 - Starts continuous I2S transfer. Also starts MCK generator when this is enabled.

tasks_stop: TASKS_STOP

0x04 - Stops I2S transfer. Also stops MCK generator. Triggering this task will cause the {event:STOPPED} event to be generated.

events_rxptrupd: EVENTS_RXPTRUPD

0x104 - The RXD.PTR register has been copied to internal double-buffers. When the I2S module is started and RX is enabled, this event will be generated for every RXTXD.MAXCNT words that are received on the SDIN pin.

events_stopped: EVENTS_STOPPED

0x108 - I2S transfer stopped.

events_txptrupd: EVENTS_TXPTRUPD

0x114 - The TDX.PTR register has been copied to internal double-buffers. When the I2S module is started and TX is enabled, this event will be generated for every RXTXD.MAXCNT words that are sent on the SDOUT pin.

inten: INTEN

0x300 - Enable or disable interrupt

intenset: INTENSET

0x304 - Enable interrupt

intenclr: INTENCLR

0x308 - Disable interrupt

enable: ENABLE

0x500 - Enable I2S module.
