Drift chamber readout module (see also [[BRIC]])

Maximum supported branch length: 30 readout cards.

BRICBOX send Link Control Frame (LCF) with used defined bits 8:15 as following:

||'''bit'''||'''description (send)'''||
||0||Suspend (receive buffer is full)||
||1||Enable remote data loopback **||
||2||reserved, 0||
||3||Local Error state||
||4||Local Ready state||
||5||Local RX error||
||7:6||reserved||
||8||--(b1_absent)--||
||9||--(b2_absent)--||
||10||--(b1_overflow)--||
||11||--(b2_overflow)--||
||12||--(b1_align_err)--||
||13||--(b2_align_err)--||
||14||--(b1_timeout)--||
||15||--(b2_timeout)--||
||31:16||Inverted 15:0||

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
