MSR Address
Type
Reset Value
The flags are set by internal conditions. The internal conditions are enabled if the EN bit is 1. Reading the FLAG bit returns
the value; writing 1 clears the flag; writing 0 has no effect. (See Section 3.8.4 "MSR Address 3: Error Control" on page 71
for further on ERR generation details.)

DIVIL_GLD_MSR_SMI Bit Descriptions (Continued)
Description
PIC ASMI Enable. Write 1 to enable PIC_ASMI_FLAG (bit 35) and to allow the
Extended PIC Mapper to generate an ASMI.
KEL Emulation Event ASMI Enable. Write 1 to enable KEL_EE_ASMI_FLAG (bit 34)
and to allow the KEL to generate an ASMI.
Shutdown ASMI Enable. Write 1 to enable SHTDWN_ASMI_FLAG (bit 33) and to
allow a Shutdown special cycle to generate an ASMI.
Halt ASMI Enable. Write 1 to enable HLT_ASMI_FLAG (bit 32) and to allow a Halt spe-
cial cycle to generate an ASMI.
Description
Reserved. Reads return 0. Writes have no effect.
UART1 and UART2 Error Flag. If high, records that an ERR was generated due to a
collision between the two UARTs. UART1 and UART2 are set to the same I/O address
base. No chip selects are asserted and DECODE_ERR_FLAG (bit 33) is asserted.
DECODE_ERR_EN (bit 1) must be high to generate ERR and set flag. Write 1 to clear;
writing 0 has no effect.
