Card autodetect is performed on power-on reset and link reset (5CE) and absent bits are updated.
Status bits (rx error, absent, overflow, align_err, timeout) are cleared on reset (power, 5CE).
Status bits overflow, align_err, timeout are also cleared right after LCF is sent.
Local error = b1_absent & b2_absent
