These bits indicate which of the bits in the Receive SERDES Data B register (Reg 0x0B) are valid. A “1” indicates that the
corresponding data bit is valid for Channel B.
If the Valid Data bit is set in the Receive Interrupt Status register (0x08) all eight bits in the Receive SERDES Data B register
(Reg 0x0B) are valid. Therefore, it is not necessary to read the Receive SERDES Valid B register (Reg 0x0C).The over-the-
air received order is bit 0 followed by bit 1, followed by bit 2, followed by bit 3, followed by bit 4, followed by bit 5, followed
by bit 6, followed by bit 7. This register is read-only.
Description
Received Data for Channel A. The over-the-air received order is bit 0 followed by bit 1, followed by bit 2, followed by bit 3,
followed by bit 4, followed by bit 5, followed by bit 6, followed by bit 7. This register is read-only.
