Description
The device part number. CC2400 has part number 0x001.
Gives the JEDEC manufacturer ID. The actual manufacturer ID
can be found in MANIFID[7:1], the number of continuation
bytes in MANFID[11:8] and MANFID[0]=1.
Chipcon's JEDEC manufacturer ID is 0x7F 0x7F 0x7F 0x9E
(0x9E preceded by three continuation bytes.)

Description
Reserved, write as 0.
Sync word detection occurs when the number of bits in the sync
word correlator different from that specified by the SYNC
registers is equal to or lower than SYNC_ERRBITS_ALLOWED.
Selects between un-buffered mode, buffered mode or test mode.
The pin configuration is set according to Table 15.
0: Un-buffered mode
1: Buffered mode
2: HSSD test mode
3: Unused
When this bit is set the packet mode is enabled. The pin
configuration is set according to Table 15.
In TX, this enables preamble generation, sync word, and CRC
appending (if enabled by CRC_ON) in the buffered mode.
In RX, this enables sync word detection in buffered and un-
buffered modes, and CRC verification (if enabled by CRC_ON) in
buffered mode.
The number of preamble bytes ("01010101") to be sent in packet
mode:
000: 0 001: 1 010: 2 011: 4
100: 8 101: 16 110: 32 111: Infinitely on
The size of the packet mode sync word sent in TX and correlated
against in RX:
00: The 8 MSB bits of SYNC_WORD.
01: The 16 MSB bits of SYNC_WORD.
10: The 24 MSB bits of SYNC_WORD.
11: The 32 MSB bits of SYNC_WORD.
In packet mode a CRC is calculated and is transmitted after the
data in TX, and a CRC is calculated during reception in RX.
