PCM Slots and Sample Formats
NEMO can receive and transmit on any selection of the first four slots following each sync pulse.
Slot durations can be either 8 or 16 clock cycles. Durations of 8 clock cycles may only be used
with 8-bit sample formats. Durations of 16 clocks may be used with 8-bit, 13-bit or 16-bit sample
formats. NEMO supports 13-bit linear, 16-bit linear and 8-bit μ-law or A-law sample formats.
The sample rate is 8ksamples/s. The bit order may be little or big endian. When 16-bit slots are
used, the 3 or 8 unused bits in each slot may be filled with sign extension, padded with zeros or a
programmable 3-bit audio attenuation compatible with some Motorola CODECs.
