ST-BUS Analyser Mask. This is the mask bit for the F0STVS status bit in the ST-BUS Interrupt
Vector Register (address 913). If this mask bit is one, the corresponding Interrupt Vector status bit
will remain inactive (zero). If this mask bit is zero, the corresponding Interrupt Vector status bit will
function normally.
ST-BUS Loopback 8M All. If one, DSTo[0] is connected to DSTi[4], and DSTo[4] is connected to
DSTi[0]. This can be used in 8.192 Mbit/s or 2.048 Mbit/s mode. See Loopbacks section.
ST-BUS Loopback Framer 6 & 7. If one, DSTo[6] is connected to DSTi[7], and DSTo[7] is
connected to DSTi[6]. Used only in 2.048Mb/s mode. See Loopback section for details.
ST-BUS Loopback Framer 4 & 5. If one, DSTo[4] is connected to DSTi[5], and DSTo[5] is
connected to DSTi[4]. Used only in 2.048Mb/s mode. See Loopbacks section.
ST-BUS Loopback Framer 2 & 3. If one, DSTo[2] is connected to DSTi[3], and DSTo[3] is
connected to DSTi[2]. Used only in 2.048Mb/s mode. See Loopbacks section.
ST-BUS Loopback Framer 0 & 1. If one, DSTo[0] is connected to DSTi[1], and DSTo[1] is
connected to DSTi[0]. Used only in 2.048Mb/s mode. See Loopbacks section.
Remote Loopback 8 Framers. If one, TPOS[0]/TNEG[0] are connected to RPOS[4]/RNEG[4],
and TPOS[4]/TNEG[4] are connected to RPOS[0]/RNEG[0]. This is used especially for 8.192
Mbit/s mode but may also be used in 2.048 Mbit/s mode. See Loopbacks section.
Remote Loopback Framer 6 & 7. If one, TPOS[6]/TNEG[6] are connected to RPOS[7]/
RNEG[7], and TPOS[7]/TNEG[7] are connected to RPOS[6]/RNEG[6]. Used only in 2.048Mb/s
mode. See Loopbacks section.
Remote Loopback Framer 4 & 5. If one, TPOS[4]/TNEG[4] are connected to RPOS[5]/
RNEG[5], and TPOS[5]/TNEG[5] are connected to RPOS[4]/RNEG[4]. Used only in 2.048Mb/s
mode. See Loopbacks section.
Remote Loopback Framer 2 & 3. If one, TPOS[2]/TNEG[2] are connected to RPOS[3]/
RNEG[3], and TPOS[3]/TNEG[3] are connected to RPOS[2]/RNEG[2]. Used only in 2.048Mb/s
mode. See Loopbacks section.
Remote Loopback Framer 0 & 1. If one, TPOS[0]/TNEG[0] are connected to RPOS[1]/
RNEG[1], and TPOS[1]/TNEG[1] are connected to RPOS[0]/RNEG[0]. Used only in 2.048Mb/s
mode. See Loopbacks section.
