213 / 234 page ![]() CC2430 CC2430 PRELIMINARY Data Sheet (rev. 1.03) SWRS036A Page 213 of 232 Bit Name Reset R/W Description 7:5 - 0 R0 Reserved, read as 0. 4 ADI_RADIO_PD 0 R ADI_RADIO_PD is a delayed version of RREG_RADIO_PD. The delay is set by RREG_DELAY[2:0]. When ADI_RADIO_PD is 0, all analog modules in the radio are set in power down. ADI_RADIO_PD is read only. 3 RREG_RADIO_PD 1 R/W Power down of the voltage regulator to the analog part of the radio. This signal is used to enable or disable the analog radio. 0 : Power up 1 : Power down 2:0 RREG_DELAY[2:0] 100 R/W Delay value used in power-on for voltage regulator VREG_DELAY[2:0] Delay Units 000 0 µs 001 31 µs 010 63 µs 011 125 µs 100 250 µs 101 500 µs 110 1000 µs 111 2000 µs Table 67: Register RFPWR (0xDF17) Bit Name Reset R/W Description 7:5 TC_RXCHAIN2RX[2:0] 011 R/W The time in 5 us steps between the time the RX chain is enabled and the demodulator and AGC is enabled. The RX chain is started when the band pass filter has been calibrated (after 6.5 symbol periods). 4:2 TC_SWITCH2TX[2:0] 110 R/W The time in advance the RXTX switch is set high, before enabling TX. Unit is µs. 1:0 TC_PAON2TX[3:2] 10 R/W The time in advance the PA is powered up before enabling TX. Unit is µs. Table 68: Register FSMTCH (0xDF20) Bit Name Reset R/W Description 7:6 TC_PAON2TX[1:0] 10 R/W The time in advance the PA is powered up before enabling TX. Unit is µs. 5:3 TC_TXEND2SWITCH[2:0] 010 R/W The time after the last chip in the packet is sent, and the rxtx switch is disabled. Unit is µs. 2:0 TC_TXEND2PAOFF[2:0] 100 R/W The time after the last chip in the packet is sent, and the PA is set in power-down. Also the time at which the modulator is disabled. Unit is µs.
