MC68HC11G5
3.4.2
This normal operating mode is established by having a logic one level on both the MODB/V
and the MODA/LIR pin at the rising edge of RESET. The ROMON bit in the CONFIG register is a
zero in this mode so that the user ROM does not appear in the map. The initial memory map which
results is also controlled by the state of three bits (RBOOT, SMOD, and MDA) in the HPRIO control
register which are initialized automatically by hardware prior to the rising edge on RESET.
Initial conditions affecting the memory map are:

$E000

$FFFF

ROMON = 0, RBOOT = 0, SMOD = 0, MDA = 1
