CC2400
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.
