NAME
defining pattern of word select signal output at WS0 pin; if WS0 pin is input and trigger, WS0 bit is
meaningless
defining pattern of word select signal output at WS1 pin
defining pattern of word select signal output at WS2 pin
defining pattern of word select signal output at WS3 pin
defining pattern of word select signal output at WS4 pin: if WS4 pin is input and trigger, WS4 bit is
meaningless
select serial data input from:
buffer:
Define on which SD pin the serial output data will appear: if both circuits attempt to drive the same
SD pin in the same time slot, A1 gets preference. When a SD pin is not driven actively it is 3-stated.
Drive the SD pin which was driven in the previous time slot as output: for 7-bit clock cycles to active
LOW and let then go to 3-state.
End Of Superframe: last record in time slot list, next time slot uses first record of the TSL (reset TSL
pointer).

0: do not load this byte into the Dword buffer
1: load this byte into the Dword buffer, place into the next available position
0: do not load this byte into the intermediate feedback buffer
1: load this byte into the intermediate feedback buffer, place into the next available position
0: do nothing
1: store Dword buffer into input FIFO, at the next available position
