Field Documentation

ca_ocd_pulldown_offset

uint8_t gddr_cal_entry_t::ca_ocd_pulldown_offset

CA driver strength as 3-bit OCD pulldown offset code (0-3 = 0..+3, 4-7 = -4..-1).

ca_termination_offset

uint8_t gddr_cal_entry_t::ca_termination_offset

CA termination offset (MR3, 0-3).

ca_vrefc_offset

uint8_t gddr_cal_entry_t::ca_vrefc_offset

CA VREFC offset as 4-bit two's-complement MR10 OP[3:0] code.

valid

uint8_t gddr_cal_entry_t::valid

1 = entry holds latched/provisioned settings, 0 = unset.
