DESCRIPTION

7

gfsk float

Controls the T_GFSK output outside TX packet. If gfsk = 0, then output tied to ground. If

gfsk = 1, then output floats.

6

grst

GFSK table address reset. Writing a logic 1 will reset the GFSK table addressing.

5

pa float

Controls the PA output outside TX packet. If pa float = 0, then output tied to ground. If

pa float = 1, then output floats.

4

clk en

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.

test.2

These 3 bits are used for test purposes.
