Revision 1.1.0

4.1.28. Destination GUID[1] (regDESTGUID[1])

regNVDESTGUID[1] (0x1F)

regDESTGUID[1] (0x6A)

R/W

Default Destination GUID[1]: 0xFF

When MAC addressing is invoked, this register holds byte 1 of the 32-bit destination GUID. This register is

used in conjunction with Destination GUID[3-2] and Destination GUID[1] registers to make up the module’s

32-bit destination GUID. For more information on the operation of addressing modes, please refer to the

Addressing Modes section of this document.

4.1.29. Destination GUID[0] (regDESTGUID[0])

regNVDESTGUID[0] (0x20)

regDESTGUID[0] (0x6B)

R/W

Default Destination GUID[0]: 0xFF

When MAC addressing is invoked, this register holds the least significant byte of the 32-bit destination

GUID. This register is used in conjunction with Destination GUID[3-1] registers to make up the module’s

32-bit destination GUID. For more information on the operation of addressing modes, please refer to the

Addressing Modes section of this document.

4.1.30. Exception Mask (regEXCEPTIONMASK)

regNVEXCEPTIONMASK (0x21)

regEXCEPTIONMASK (0x6C)

R/W

Default Exception Mask: 0xFF

The module has a built-in exception engine that can notify the host processor of an unexpected event.

When an exception occurs, this register is ANDed with the exception code. A non-zero result causes an

assertion of the EX pin. Reading the regEXCEPTION register will clear the exception and return the EX

pin to low. If the result is zero, the EX pin is not asserted, but the exception code is stored in the

regEXCEPTION register.
