These 5 bits are reserved and are not to be used.
Baseband ready. This bit is used to control the function of SYS_CLK_REQ.
These 2 bits are reserved and are not to be used.
Controls the T_GFSK output outside TX packet. If gfsk = 0, then output tied to ground. If
gfsk = 1, then output floats.
GFSK table address reset. Writing a logic 1 will reset the GFSK table addressing.
Controls the PA output outside TX packet. If pa float = 0, then output tied to ground. If
pa float = 1, then output floats.
Enables the 2.048 MHz clock on T_SW. If clk en = 0, then pin T_SW = T_SW. If
clk en = 1, then pin T_SW = 2.048 MHz.
These 3 bits are used for test purposes.
This bit is reserved and should not be used.
