*RBOOT, SMOD, and MDA reset depend on power-up initialization mode.
RBOOT — Read Bootstrap ROM
SMOD — Special Mode Select
MDA — Mode Select A
Bit 4 — Not implemented
Always reads zero.
PSEL[3:0] — Priority Select Bits [3:0]
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.
HPRIO — Highest Priority I-Bit Interrupt and Miscellaneous
