Function

PC is corrupted when single-stepping through an instruction that clears the GIE bit

Description

Single-stepping over an instruction that clears the General Interrupt Enable bit (for example DINT or BIC #GIE,SR) when the GIE bit was previously set may corrupt the PC.  For example, the DINT or BIC #GIE,SR is a 2-byte instruction. Single stepping through this instruction increments the PC by a value of 4 instead of 2 thus corrupting the next PC value.

Note: This erratum applies to debug mode only.

Workaround

Insert a NOP or __no_operation() intrinsic immediately after the line of code that clears the GIE bit.

OR

Refer to the table below for compiler-specific fix implementation information.
Note that compilers implementing the fix may lead to double stack usage when RET/RETA follows the compiler-inserted NOP.
