30 Asynchronous and Synchronous Serial Operation
Several features and modes of operation have
been included in the CC2500 to provide
backward compatibility with previous Chipcon
products and other existing RF communication
systems. For new systems, it is recommended
to use the built-in packet handling features, as
they can give more robust communication,
significantly offload the microcontroller and
simplify software development.
30.1
Asynchronous Operation
For backward compatibility with systems
already using the asynchronous data transfer
from other Chipcon products, asynchronous
transfer is also included in CC2500 . When
asynchronous transfer is enabled, several of
the support mechanisms for the MCU that are
included in CC2500 will be disabled, such as
packet handling hardware, buffering in the
FIFO and so on. The asynchronous transfer
mode does not allow the use of the data
whitener, interleaver, and FEC, and it is not
possible to use Manchester encoding.
Note
that
MSK
is

asynchronous transfer.
Setting
PKTCTRL0.PKT_FORMAT
enables asynchronous serial mode.
In TX, the GDO0 pin is used for data input (TX
data). Data output can be on GDO0, GDO1 or
GDO2. This is set by the IOCFG0.GDO0_CFG,
IOCFG1.GDO1_CFG and IOCFG2.GDO2_CFG
fields.
The CC2500 modulator samples the level of the
asynchronous input 8 times faster than the
programmed data rate. The timing requirement
for the asynchronous stream is that the error in
the bit period must be less than one eighth of
the programmed data rate.
31 System Considerations and Guidelines
31.1
SRD Regulations
International regulations and national laws
regulate the use of radio receivers and
transmitters. The most important regulations
for the 2.4 GHz band are EN 300 440 and EN
300 328 (Europe), FCC CFR47 part 15.247
and 15.249 (USA), and ARIB STD-T66
(Japan). A summary of the most important
30.2
Setting
enables synchronous serial mode. In the
synchronous serial mode, data is transferred
on a two wire serial interface. The CC2500
provides a clock that is used to set up new
data on the data input line or sample data on
the data output line. Data input (TX data) is the
GDO0 pin. This pin will automatically be
configured as an input when TX is active. The
data output pin can be any of the GDO pins;
this is set by the IOCFG0.GDO0_CFG,
IOCFG1.GDO1_CFG and IOCFG2.GDO2_CFG
fields.
Preamble and sync word insertion/detection
may or may not be active, dependent on the
sync mode set by the MDMCFG2.SYNC_MODE.
If preamble and sync word is disabled, all
other packet handler features and FEC should
also be disabled. The MCU must then handle
preamble
detection in software. If preamble and sync
word insertion/detection is left on, all packet
handling features and FEC can be used. One
supported
for
exception is that the address filtering feature is
unavailable in synchronous serial mode.

When using the packet handling features in
synchronous serial mode, the CC2500 will
insert and detect the preamble and sync word
and the MCU will only provide/get the data
payload.
