6.30 EEM14

EEM Module

Category

Debug

Function

Single-step or breakpoint on module registers with WAIT capability may not work

Description

In debug mode, the CPU clock is driven independently from the wait inputs of device modules (i.e., MULT, USB, RF1A, CRC). As a result, an EEM halt on an access to the module data registers (breakpoint or single-step) may show incorrect results due to incomplete execution.

Workaround

Do not single-step through a data register access that holds the CPU to provide a valid result. Place breakpoints after the affected register is accessed and sufficient clock cycles have been provided.

Note: This erratum applies to debug mode only.
