Revision 1.1.0

4. Module Configuration

The Wi.232FHSS modules will work right “out of the box” without any configuration. However, a great many

configuration registers are exposed to allow for the custom-tailoring of the wireless link. These registers are classified

as four different types: non-volatile R/W, non-volatile R/O, volatile R/W, and volatile R/O. During the power-on/reset

sequence, the non-volatile read/write registers are copied into the volatile read/write registers. This allows the

integrator to determine a default configuration for the wireless link that can be preset at the factory, requiring no

intervention by the host processor. During operation, changes to the volatile read/write registers have an immediate

effect on the Wi.232FHSS parameters. Non-volatile read-only registers provide a way for the host application to

retrieve information about the module hardware, firmware, and hard-coded configuration parameters such as the

MyGUID address.

4.1. Register Descriptions

4.1.1. CRC Error Count (regCRCERRCOUNT)

regCRCERRCOUNT (0x40)

R/W

The value in this register is augmented each time a packet is received that fails CRC check. Writing 0x00

to this register will initialize the count.

4.1.2. Channel Hop Table (regHOPTABLE)

regNVHOPTABLE (0x00)

regHOPTABLE (0x4B)

R/W

RES

Default hop sequence: 0

The Wi.232FHSS supports 6 different hop sequences with minimal correlation. Changing the hop

sequence changes the physical band utilization, much the same way that a channel does in a static

transmitter. Valid values are 0-5.
