RESET:
Refer to 2 Operating Modes.
Refer to 2 Operating Modes.
Refer to 2 Operating Modes.
Always reads zero.
Can be written only while the I bit in the CCR is set (interrupts disabled). These bits select one interrupt
source to be elevated above all other I-bit related sources.
RBOOT*
*RBOOT, SMOD, and MDA reset depend on power-up initialization mode.
