4.3.2.13 Local Bus Transfer Error Status and Control Register 2 (L_TESCR2)
The local bus transfer error status and control register 2 (L_TESCR2) is shown in Figure 4-34 .
Table 4-18 describes L_TESCR2 fields.
17 DMD Data errors disable. Setting this bit disables parity errors on the local bus.
18–19 — Reserved, should be cleared.

m (HiP3) Rev A.1 silicon: reserved, should be cleared.
DER .29
µ
m (HiP3) Rev B.3 silicon and forward: Data error. Set when a core machine check is asserted
due to parity errors in the local bus.
21–31 — Reserved, should be cleared.

Bits Name Description
0–11 — Reserved, should be cleared.
12–15 PB Parity error on byte. There are four parity error status bits, one per 8-bit lane. A bit is set for the byte
that had a parity error.
16–27 BNK Memory controller bank. There are twelve error status bits, one per memory controller bank. A bit is
set for the local bus memory controller bank that had an error. Note that BNK is invalid if the error
was not caused by ECC or PARITY checks.
28–31 — Reserved, should be cleared.
