Memory Write Data
values (bits 11 to 8); in a write memory access
the values to transfer are written to these registers. Both registers
must not be written during an active access. An active access cycle,
started by a write access to MACH, is indicated by register bit
STAR:MAC.
If the values MWD10..0 / MRD10..0 are used as control memory entries, each possible
value corresponds to a single input time slot. MWD11 / MRD11 defines, whether the
input time slot is switched actively to the PCM output or is switched to high impedance.
Table 13
Input Time Slot Mapping / Programming of Output Tristate Control
TSC
Tristate Control Value
0: active
1: high impedance;
TSC controls whether the output time slot (corresponding to the
address of the control memory location) will drive the PCM values or
will be tristate.
