(43) Estimate control register (BBEVAREG)
This register is used to set the evaluation mode which is required when obtaining the certification of
conformance to technical standards.
Setting “1” to both continuous transmission mode and transmit trigger bit enters into the continuous
transmission mode. In the continuous transmission mode, the data of the number subtracted CRC byte
count from the value
set in the transmission frame length is repetitively transmitted. Note that the transmission data is the value
which is written in the transmit RAM.Reset by RFRESETB pin after stopping the continuous transmission
mode.
The non-modulation switch bit can switch between the modulation signal and non-modulation signal.
Setting “1” to both continuous receive mode bit and receive trigger bit enters into the continuous receive
mode. In the continuous receive mode, the completion of the data reception cannot enter into the IDLE
state. The receive state is left as it is.
Setting “1” to both special transmission mode and transmit trigger bit can transmit frames regardless of the
IEEE802.15.4 standard.
Setting “1” to both special receive mode bit and receive trigger bit can receive frames regardless of the
IEEE802.15.4 standard.
The BBEVAREG register is set by the serial interface in 8-bit units.
Reset signal generation clears this register to 00H.
