LRCK_
TPWH[10:3]
LRCK high-time pulse width [10:3]. With LRCK_TPWH[2:0], sets the number of SCLK cycles for which the LRCK remains
high. Active only when in TDM Mode and LRCK_50_NPW = 1.
0x000 (Default) LRCK high time is 1 SCLK wide
0x001 LRCK high time is 2 SCLKs wide

LRCK_50_NPW
LRCK either 50% duty cycle or programmable high-time pulse width. In TDM Mode, pulse width can be 50% or
programmable up to 2047 x SCLK cycles.
0 (Default) High-time pulse width set by LRCK_TPWH[10:0].
1 50% duty cycle
2:0 LRCK_TPWH[2:0] LRCK high time pulse width [2:0]. With LRCK_TPWH[10:3], sets the LRCK high time in TDM Mode. See
