6.34 DMA8

DMA Module

Category

Functional

Function

DMA can corrupt values on write-access to program stack

Description

If the DMA controller makes a write access to the stack while executing one of the following instructions, the data that is written may be corrupted.

CALLA   [REG | IDX | SYM | ABS | IND | INA | IMM]
PUSHX.A [IDX | SYM | ABS | IND | IMM | INA]
PUSHX.A [REG]
PUSHM.A [REG]
POPM.A  [REG]

Note: [ ... ] denotes an addressing mode

Workaround

Do not declare function-scope variables. Declare all variables that are intended to be modified by the DMA as global- or file-scope such that they are allocated in the data section of RAM and not on the program stack.
