a) With TCBL set to input, driving TCBL high for >3 OMCK clocks will cause a frame start, as well as a new
channel status block start.
b) If the serial audio input port is in Slave Mode and TCBL is set to output, the start of the A channel sub-
frame will be aligned with the leading edge of ILRCK.
The timing of TCBL, VLRCK, C, U, and V are illustrated in
tual word clock signal, and is used here only to illustrate the timing of the C, U, and V bits. In Stereo Mode
VLRCK = AES3 frame rate and in Mono Mode VLRCK = 2 x AES3 frame rate. If the serial audio input port
is set to Slave Mode and TCBL is an output, VLRCK = ILRCK when SILRPOL = 0 and VLRCK = ILRCK
when SILRPOL = 1. If the serial audio input port is set to master mode and TCBL is an input,
VLRCK = ILRCK when SILRPOL = 0 and VLRCK = ILRCK when SILRPOL = 1.
