bits 0–28
Reserved.
MDATRQS
MLB Data eDMA Request Status. This bit indicates the state of the internal eDMA request signal. It is free
running and high for 16 bits of the MLBCLK signal then low for the following 16 bits. MDATRQS is cleared when
MDIS is set. MDATRQS will only be set after MSYSS is set.
0 eDMA request is not asserted
1 eDMA request is asserted
MSYSS
MLB System Stable. This signal is asserted by the hardware after it detects 256 occurrences of the
FRAMESYNC pattern (0x1FE). It can be cleared only by setting MDIS.
0 System is not stable
1 System is stable
MSVRQS
MLB Service Request Status. This bit indicates the state of the internal SRV_REQ_GLUE signal. It is high for 16
bits of the MLBCLK signal then low for the following 16 bits. SRV_REQ is MSVRQS gated with MSVRQIE.
Likewise, SRV_REQ_CI is MSVRQS gated with MSVRQCIE and MSVRQIE. MSVRQS is cleared when MDIS is
set. MSVRQS will only be set after MSYSS is set.
0 Service request not active
1 Service request active
