| |
Each of these registers contains a single value, but not the entire 8 bits:
DP_PAYLOAD_ALLOCATE_SET - Bit 7 Reserved DP_PAYLOAD_ALLOCATE_START_TIME_SLOT - Bits 7:6 Reserved DP_PAYLOAD_ALLOCATE_TIME_SLOT_COUNT - Bits 7:6 Reserved
Add definitions to properly mask off values read from these registers.
