Highest priority interrupt (HPRIO) $003C
10.5.1 HPRIO — Highest priority I-bit interrupt and misc. register
MC68HC11P2 — Rev 1.0
RBOOT, SMOD, and MDA bits depend on power-up initialization mode
and can only be written in special modes when SMOD = 1. Refer to
Table
RBOOT — Read bootstrap ROM (refer to
Chip
SMOD — Special mode select (refer to
Memory)
MDA — Mode select A (refer to
Memory)
PSEL[4:0] — Priority select bits
Freescale Semiconductor, Inc.
These bits select one interrupt source to be elevated above all other
I-bit-related sources and can be written to only while the I-bit in the
CCR is set (interrupts disabled). See
Address bit 7

1 = Bootloader ROM enabled, at $BE40–$BFFF.
0 = Bootloader ROM disabled and not in map.
1 = Special mode variation in effect.
0 = Normal mode variation in effect.
1 = Normal expanded or special test mode in effect.
0 = Normal single chip or special bootstrap mode in effect.
