Enhanced Synchronous Serial Interface (ESSI)
ESSI Programming Model
MOTOROLA
DSP56309UM/D 7-9
¥ Three transmit data registers (TX0, TX1, TX2)
¥ One receive data register (RX)
¥ Two transmit slot mask registers (TSMA, TSMB) illustrated in
¥ Two receive slot mask registers (RSMA, RSMB) illustrated in
¥ One special-purpose time slot register (TSR)
The following paragraphs give detailed descriptions and operations of each of the bits in
the ESSI registers. The GPIO functionality of the ESSI is documented in
