Result Data:
30.5.3.3.12Write Debug Module Register (
The operand (longword) data is written to the specified debug module register. All 32 bits of the
register are altered by the write. DSCLK must be inactive while the debug module register writes
from the CPU accesses are performed using the WDEBUG instruction.
