49 Configuration Registers

The configuration of

CC2400 is done by

programming

the

16-bit

configuration

registers. The configuration data based on

selected system parameters are most

easily found by using the SmartRF® Studio

software. Complete descriptions of the

registers are given in the following tables.

After a RESET is programmed, all the

registers have default values as shown in

the tables.

Some registers are Strobe Command

Registers. Accessing these registers will

initiate the change of an internal state or

mode.

The FIFO is accessed as an 8-bit register.

Some registers contain signed values.

These are in two’s complement format. I.e.

for a 4-bit value, 0000 is 0, 1111 is –1,

1110 is –2, 1000 is -8 and 0111 is 7.

During the address transfer a status byte

is returned. This status byte is described

in Table 13 at page 23.
