The individual sub-fields are described below:
Description of fields within Register file: 0x1F – Channel Control
TX_CHAN
reg:1F:00
bits:3–0
This selects the transmit channel. Supported channels are 1, 2, 3, 4, 5, and 7. Other values
should not be used. Both TX_CHAN and RX_CHAN (below) should be set to the same value.
Full selection of TX channel requires that the following parameters are also set appropriately:
Sub-Register 0x28:0C– RF_TXCTRL
Sub-Register 0x2A:0B – TC_PGDELAY
Sub-Register 0x2B:07 – FS_PLLCFG
For correct operation of the DW1000 and compliance to the IEEE 802.15.4 UWB standard, the
preamble code should be set according to the operating channel. For details of centre
frequencies and preamble codes for the supported channels, please refer to section 10.5 –
UWB channels and preamble codes.
RX_CHAN
reg:1F:00
bits:7–4
This selects the receive channel. Supported channels are 1, 2, 3, 4, 5, and 7. Other values
should not be used. Both RX_CHAN and TX_CHAN (above) should be set to the same value.
Full selection of RX channel requires that the following parameters are also set appropriately:
Sub-Register 0x28:0B– RF_RXCTRLH
Sub-Register 0x2B:07 – FS_PLLCFG
For correct operation of the DW1000 and compliance to the IEEE 802.15.4 UWB standard, the
preamble code should be set according to the operating channel. For details of centre
frequencies and preamble codes for the supported channels, please refer to section 10.5 –
UWB channels and preamble codes.
Bits marked ‘-’ in register 0x1F are reserved.
