XC161, Does a PEC transfer interrupt a EXTS Sequence

Ferdinand Triller

My application needs very fast PEC response times.

As i can see in the ".lst" file, the Keil compiler uses EXTS sequences for long addressing memory access:

EXTS #014H, #04H
MOV R5, [R9]
MOV R6, [R9 + #SOF(02H)]
MOV R7, [R9 + #SOF(04H)]
MOV R8, [R9 + #SOF(06H)]

What happens, if a PEC event occurs during the EXTS seqence? Does the PEC transfer interrupt the EXTS Sequence, or is the PEC tranfer delayed until the EXTS sequence is finished?
