14.10.8 Peripheral Module Disable
Both the CRC and scanner module can be disabled individually by setting the CRCMD and SCANMD bits of the PMD0 register. The SCANMD can be used to enable or disable to the scanner module only if the SCANE bit of Configuration Word 4 is set. If the SCANE bit is cleared, then the scanner module is not available for use and the SCANMD bit is ignored.
