4.2.2.1 RAM
The MC68HC11F1 microcontroller has 1024 bytes of fully static RAM that can be used
for storing instructions, variables, and temporary data during program execution. RAM
can be placed at any 4-Kbyte boundary in the 64 Kbyte address space by writing an
appropriate value to the INIT register.
RAM is initially located at $0000 in the memory map upon reset. Direct addressing
mode can access the first 256 locations of RAM using a one-byte address operand.
Direct mode accesses save program memory space and execution time.
The on-chip RAM is a fully static memory. RAM contents can be preserved during pe-
riods of processor inactivity by either of two methods, both of which reduce power con-
sumption.
NOTES:
1. RAM can be remapped to any 4-Kbyte boundary ($x000). "x" represents the value contained in
RAM[3:0] in the init register.
2. The register block can be remapped to any 4-Kbyte boundary ($y000). "y" represents the value contained in
reg[3:0] in the init register.
3. Special test mode vectors are externally addressed.
4. In special test mode the address locations $zD00–$zDFF are not externally addressable.
"z" represents the value of bits EE[3:0] in the config register.
5. EEPROM can be remapped to any 4-Kbyte boundary ($z000). "z" represents the value contained in
EE[3:0] in the config register.
