GLD_MSR_ERROR Bit Descriptions
Bit
Name
Description
63:36
RSVD
Reserved.
35
ERR_SYSPLL
Error System PLL. System PLL lock signal was active when POR was inactive.
Writing 1 clears error; 0 leaves unchanged.
34
ERR_DOTPLL
Error Dot Clock PLL. Dot clock PLL lock signal was active when POR was inac-
tive. Writing 1 clears error; 0 leaves unchanged.
33
ERR_SIZE
Error Size. The GLIU interface detected a read or write of more than 1 data
packet (size = 16 bytes or 32 bytes). If a response packet is expected, the excep-
tion bit will be set, in all cases the asynchronous error signal will be set. Writing 1
clears error; 0 leaves unchanged.
32
ERR_TYPE
Error Type. An unexpected type was sent to the GLCP GLIU interface (start
request with BEX type, snoop, peek_write, debug_req, or NULL type). If a
response packet is expected, the exception bit will be set, in all cases the asyn-
chronous error signal will be set. Writing a 1 clears the error, writing a 0 leaves
unchanged.

RSVD
Reserved.
3
ERR_SYSPLL_MASK
Error System PLL Mask. When set to 1, disables error signaling based on the
state of the ERR_SYSPLL flag (bit 35).
2
ERR_DOTPLL_MASK
Error Dot Clock PLL Mask. When set to 1, disables error signaling based on the
state of the ERR_DOTPLL flag (bit 34).
1
ERR_SIZE_MASK
Error Size Mask. When set to 1, disables error signaling based on the state of
the ERR_SIZE flag (bit 33).
0
ERR_TYPE_MASK
Error Type Mask. Wh.en set to 1, disables error signaling based on the state of
the ERR_TYPE flag (bit 32).
