10.2.5.16 ATPL360_REG_TONE_MAP_RSP_DATA (0x4005)

Tone Map response data is the best modulation and Tone Map combination to maximize baud rate and minimize frame error rate. It is calculated by the selection algorithm, based on the signal quality of the last received message. See ATPL360_REG_TONE_MAP_RSP_ENABLED_MODS (0x403E) to enable/disable the different modulations for the selection algorithm.

The format is defined by the structure shown below (fields and related constants are explained in PHY-DATA.request):

typedef struct tm_rsp_data {
        enum mod_types uc_mod_type;
        enum mod_schemes uc_mod_scheme;
        uint8_t puc_tone_map[TONE_MAP_SIZE_MAX];
} tm_rsp_data_t;

Access: Read-only.

Value Range: 5 bytes.

Default Value: BPSK Robust modulation type (0x04), differential modulation scheme (0x00) and full tone map (0x3F0000 in CENELEC-A; 0x0F0000 in CENELEC-B; 0xFFFFFF in FCC; 0xFFFF03 in ARIB).
