VERSION
1)
Bit 7
A crash occurs, if 2 or more channels are programed to transmit (talk) in the same time slot on the same
highway. In this case the crash-bit will be set, and transmission will be disabled for all affected channels.
XR5 Extended Register 5
MCLK-SEL
Selects Master Clock frequency, that has to be applied to pin MCLK
The MCLK signal has to synchronous to the 8 kHz FSC-signal.
