M68HC11E Family — Rev. 3.2
MOTOROLA
Resets:
Single chip:
1. The reset values depend on the mode selected at the RESET pin rising edge.
Expanded:
Bootstrap:
Address:
RBOOT — Read Bootstrap ROM Bit
SMOD and MDA — Special Mode Select and Mode Select A Bits
Read:
Write:
Figure 4-9. Highest Priority I-Bit Interrupt and Miscellaneous
Test:
Valid only when SMOD is set (bootstrap or special test mode); can be
written only in special modes
The initial value of SMOD is the inverse of the logic level present on
the MODB pin at the rising edge of reset. The initial value of MDA
equals the logic level present on the MODA pin at the rising edge of
reset. These two bits can be read at any time. They can be written
anytime in special modes. MDA can be written only once in normal
modes. SMOD cannot be set once it has been cleared.
0 = Bootloader ROM disabled and not in map
1 = Bootloader ROM enabled and in map at $BE00–$BFFF
