19.13 Peripheral Module Disable
Both the CRC and scanner module can be disabled individually by setting the CRCMD and SCANMD bits of one of the PMD registers (see the “PMD - Peripheral Module Disable” chapter for more details). The SCANMD bit can be used to enable or disable the scanner module only if the SCANE Configuration bit is set. If the SCANE bit is cleared, then the scanner module is not available for use and the SCANMD bit is ignored.
