TxDataAccess
Title:
Tx Data path Access point.
Address:
$0x50 to $0x53 (mapped over 4 locations)
Function:
RW
Description:
This register block allows direct access to the Tx Data path values just after the gain, phase and
offset adjustment block. Both read and write operations are permitted. A read operation reads
the signal values on the I and Q channels. A write operation will write data to the data path just
before the 15-tap filter. To prevent normal Tx data overwriting this value the TxDPAccessSel bit
in the LoopBackCtrl register should be set active. The MSB read data register is buffered to
enable access to a discrete sample value (if this register was not buffered, data from different
sample periods could be in the MSB and LSB registers). Therefore the LSB register must be
read first for correct operation.
