Up Vortex Error. This field is a composite
error field of possible Up Turbo Vortex errors
that the ICR gate array can detect. There are
two separate Up Turbo Vortex buses, one for
hose<3:2> and one for hose<1:0>.
An IPL 17 interrupt is generated when these
bits set if interrupts are enabled by
INTR_NSES (ICCNSE<31>). The I/O port
should be reset if this error bit is set. The
possible Up Turbo Vortex errors are as follows:
<24:23>
W1C, 0
Down Vortex Error. This field is a composite
error field of possible Down Turbo Vortex er-
rors that the Down HDR gate arrays can de-
tect. There are two separate Down Turbo Vor-
tex buses, one for hose<3:2> and one for
hose<1:0>.
An IPL 17 interrupt is generated when these
bits set if interrupts are enabled by
INTR_NSES (ICCNSE<31>). The I/O port
should be reset if this error bit is set. The
possible Down Turbo Vortex errors are as fol-
lows:
ICR_UP_VRTX_ERR<1> detects errors
on Up Turbo Vortex B (hose<3:2>
ICR_UP_VRTX_ERR<0> detects errors on
Up Turbo Vortex A (hose<1:0>)
Parity
Sequence error
Buffer overflow
Illegal command
DN_VRTX_ERR<1> detects errors on
Down Turbo Vortex B (hose<3:2>)
DN_VRTX_ERR<0> detects errors on
Down Turbo Vortex A (hose<1:0>)
Parity
Illegal command
Sequence error
Buffer overflow
Internal HDR error
