| Bit | Description |
|---|---|
| 7-6 | I2S enable (soft reset = %00)
%00 = off %01 = I2S is mono source right %10 = I2S is mono source left %11 = I2S is stereo |
| 5 | Reserved, must be 0 |
| 4 | 0 PCM_DOUT to Pi, PCM_DIN from Pi (Pi hats) (soft reset = 0)
1 PCM_DOUT from Pi, PCM_DIN to Pi (Pi) |
| 3 | Mute left side (soft reset = 0) |
| 2 | Mute right side (soft reset = 0) |
| 1 | Slave mode (PCM_CLK, PCM_FS supplied externally) (soft reset = 0) |
| 0 | Direct I2S audio to EAR on {{#ask:
PortNumber::$xxFE }} ($xxFE{{#ask: PortNumber::$xxFE |mainlabel=- |headers=hide |intro= / |?NumberDec#- }}) (soft reset = 0) |
(note: Next registers with number higher than $7F are inaccessible from Copper code)
