• Bit [3:0] - PDT_THRES
These register bits control the sensitivity of the receiver correlation unit. If the Antenna Diversity
algorithm is enabled (ANT_DIV_EN = 1), the value shall be set to PDT_THRES = 3, otherwise it
shall be set back to the reset value. This is not automatically done by the hardware.
Table 11-10. Receiver Sensitivity Control
Register 0x0D (ANT_DIV):
The ANT_DIV register controls Antenna Diversity.
• Bit 7 - ANT_SEL
This register bit signals the currently selected antenna path. The selection may be based either
on the last antenna diversity cycle (ANT_DIV_EN = 1) or on the content of register bits
ANT_CTRL, for details refer to
142.
Table 11-11. Antenna Diversity - Antenna Status
• Bit [6:4] - Reserved
• Bit 3 - ANT_DIV_EN
If register bit ANT_DIV_EN is set, the Antenna Diversity algorithm is enabled. On reception of a
frame the algorithm selects an antenna autonomously during SHR search. This selection is kept
until:
