Table 10-18. Bit number N in RSM (RS**) is an enable/disable control bit for receiving data
in slot number N.
When bit number N in the RSM register is cleared, the data from the enabled receivers input
pins are shifted into their receive shift registers during slot number N. The data is not
transferred from the receive shift registers to the receive data registers, and neither the RDF
nor the ROE flags are set. This means that during a disabled slot, no receiver full interrupt is
generated. The DSP is interrupted only for enabled slots.
When bit number N in the RSM is set, the receive sequence is as usual: data which is shifted
into the enabled receivers shift registers is transferred to the receive data registers and the
RDF flag is set.
Data written to the RSM affects the next received frame. The frame being received is not
affected by this data and would comply to the last RSM setting. Data read from RSM returns
the last written data.
