Proprietary Radio
Table 23-147. Proprietary Radio Operation Status Codes (continued)
Number Name
0x3805 PROP_ERROR_RXOVF
0x3806 PROP_ERROR_TXUNF
The conditions for giving each status are listed for each operation. Some of the error causes listed in
Table 23-147 are not repeated in these lists. If CMD_STOP or CMD_ABORT is received while waiting for
the start trigger, the end cause is DONE_STOPPED or DONE_ABORT, with an end result of FALSE and
ABORT, respectively. In some cases, general error causes may occur. For all these error cases, the result
of the operation is ABORT.
23.7.5.2 Proprietary Mode Setup Command
The CMD_PROP_RADIO_SETUP and CMD_PROP_RADIO_DIV_SETUP commands are used instead of
CMD_RADIO_SETUP for proprietary mode radio.
On start, the radio CPU sets up parameters for the proprietary mode with parameters given in
Table 23-140. The modulation.modType parameter selects between GFSK and unshaped FSK. For FSK
and GFSK, modulation.deviation gives the deviation in 250-Hz steps. The radio CPU uses this parameter
to calculate a proper shape for use in TX, or uses a pre-calculated shape for some typical deviations.
The symbol rate is programmed with symbolRate. The parameters are passed directly to the modem and
may be calculated using an external tool. The symbol rate is given by
f = (R × f ) / (p × 2
baud clk
where
f is the obtained baud rate
baud
f is the system clock frequency of 24 MHz
clk
R is the rate word given by symbolRate.rateWord
p is the prescaler value, given by symbolRate.preScale, which can be from 4 to 15
The rxBw parameter gives the receiver bandwidth. Values 32–52 give the supported bandwidths with the
recommended settings. Values 1–18 give the same bandwidths as settings 35–52, for the CC26xx and
CC13xx devices. The values supported and corresponding settings are summarized in
These signals are also in calculation of other register settings.
