Receive Slot Mask Registers (Rsma_1, Rsmb_1) - Motorola DSP56367 User Manual

11.3.14 RECEIVE SLOT MASK REGISTERS (RSMA_1, RSMB_1)

The Receive Slot Mask Registers (RSMA_1 and RSMB_1) are two read/write registers used
by the receiver in network mode to determine for each slot whether to receive a data word and
generate a receiver full condition (RDF=1), or to ignore the received data. RSMA_1 and
RSMB_1 should be considered as each containing half of a 32-bit register RSM_1. See Table
11-13 and Table 11-14. Bit number N in RSM_1 (RS**) is an enable/disable control bit for
receiving data in slot number N.
