TIME SLOT ASSIGNMENT/ORGANIZATION
Onboard counters establish when PCM and ADPCM
I/O occurs. The counters are programmed via the time
slot registers. Time slot size (number of bits wide) is de-
termined by the state of CP/EX. The number of time
slots available is determined by both the state of CP/EX
and U/A. (See Figures 7 through 10.) For example, if the
X channel is set to compress (CP/EX = 1) and it is set to
expect
μ
-law data (U/A = 1), then the input port (XIN) is
set up for 32 8-bit time slots and the output port (XOUT)
is set up for 64 4-bit time slots. The time slot organiza-
tion is not dependent on which algorithm has been se-
lected. NOTE: Time slots are counted from the frame
sync signal starting at the first rising edge of either CLKX
or CLKY after the frame sync.
