10.3.5.10 Channel Status Register (I2S_CH_ST_CON, R/W, Address = 0xFA14_0024)
I2S_CH_ST_CON
-
channel_status_reload
Channel status information needs to be applied to the audio stream at the IEC 60958 block boundary. For this
synchronization, there are two register sets for channel status block. You can set the channel status registers,
I2S_CH_ST_0~I2S_CH_ST_4, while the I2S Rx module still refers to the shadow channel status registers,
I2S_CH_ST_SH_0~ I2S_CH_ST_CH4.
To reflect the user configuration in the channel status registers, set 'channel_status_reload' bit in
I2S_CH_ST_CON, then I2S Rx module copies the channel status registers into the shadow channel status
registers at the beginning of an IEC-60958 block.
10.3.5.11 Channel Status Register (I2S_CH_ST_0, I2S_CH_ST_SH_0)
I2S_CH_ST_0, R/W, Address = 0xFA14_0028
I2S_CH_ST_SH_0, R, Address = 0xFA14_003C

NOTE: The bits listed here in channel status registers look swapped from those in IEC-60958-3 specification, as the bit order
is different (LSB is right-most bit).
Bit

Reserved
[0]
0 = Updates the shadow channel status registers
1 = Sets this bit to update the shadow channel status
registers with the values updated in I2S_CH_ST_0 ~
I2S_CH_ST_4.
This bit is cleared if the shadow channel status registers
are updated.

If bit1 = 0,
3b000 = 2 audio channels without pre-emphasis*

If bit1 = 1,
3b000 = default state
