Note: To load a new tau-dither value, it must be
followed by the loading of a Receiver PN code to latch
in the new Tau-Dither.
Selects one of 4 phases of the R11 sync (from the
Master’s Tx PN generator) with which to reset the
Master’s receive PN Generator when attempting to
acquire code lock with the Slave unit. This is useful in
acquisition when transitioning from R11 to R13 which is
four times as long. This specialized function is used in
the Atmel acquisition software.
0 = PA HI/LO pin 16 low.
1 = PA HI/LO pin 16 high.
Intended for control of RF transmit power to a lower
level in narrowband mode.
