System Registers 7-119

Table 7-56 ICCNSE Register Bit Definitions (Continued)

Name Bit(s) Type Function

UP_VRTX_ERR

<26:25> W1C, 0 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>.

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>)

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:

Parity

Sequence error

Buffer overflow

Illegal command

DN_VRTX_ERR

<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>.

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>)
