- * Abstract:
- * This module provides the capability to translate pure SPI response into human readable form.
- *
- * Some SPI peripherals provides simple responses, but some others provide responses depending
- * on previous command, they have obtained.
- *
- * So we have a structure, that maps SPI peripheral names (spi port names) to arrays of another
- * structure, that maps spi commands to responses field descriptors.
- *
- * Command to response field map consists of a command mask, command, pointer to field
- * descriptor and number of fields in field descriptor.
- *
- * Each fields descriptor maps field name to field mask, that specifies the meaning of each
- * bit or group of bits in the response.
