Read: Anytime
Write: Bits 7,1,0 anytime, Bit 6 can be written anytime but always reads back as 0.
Bits 5:2 anytime DBG is not armed.
NOTE
When disarming the DBG by clearing ARM with software, the contents of
bits[5:2] are not affected by the write, since up until the write operation,
ARM=1 preventing these bits from being written. These bits must be cleared
using a second write if required.
