0x36 (0xF6): WORTIME1 – High Byte of WOR Time
Reset
R/W Description
R
High byte of timer value in WOR module
Bit Field Name
7:0 TIME[7:0]
0x37 (0xF7): WORTIME0 – Low Byte of WOR Time
Reset
R/W Description
R
Low byte of timer value in WOR module
0x38 (0xF8): PKTSTATUS – Current GDOx Status and Packet Status
Bit Field Name
Reset
R/W Description
7 CRC_OK
6 CS
5 PQT_REACHED
4 CCA
3 SFD
2 GDO2
1 Reserved
0 GDO0
R
The last CRC comparison matched. Cleared when
entering/restarting RX mode. Only valid if
PKTCTRL0.CC2400_EN=1.
R
Carrier sense
R
Preamble Quality reached
R
Channel is clear
R
Sync word found
R
Current GDO2 value. Note: the reading gives the non-inverted
value irrespective what IOCFG2.GDO2_INV is programmed to.
It is not recommended to check for PLL lock by reading
PKTSTATUS[2] with GDO2_CFG=0x0A.
R0
R
Current GDO0 value. Note: the reading gives the non-inverted
value irrespective what IOCFG0.GDO0_INV is programmed to.
It is not recommended to check for PLL lock by reading
PKTSTATUS[0] with GDO0_CFG=0x0A.
0x39 (0xF9): VCO_VC_DAC – Current Setting from PLL Calibration Module
Bit Field Name
Reset
R/W Description
7:0 VCO_VC_DAC[7:0]
R
Status register for test only
0x3A (0xFA): TXBYTES – Underflow and Number of Bytes
Bit Field Name
Reset
R/W Description
7 TXFIFO_UNDERFLOW
6:0 NUM_TXBYTES
R
R
Number of bytes in TX FIFO
