Table 31. Memory Mapped Registers and their Register Bit Definitions
1. The FMS7401L’s normal mode operation begins after a system reset and is when the 8-bit microcontroller core begins executing the instruction program residing
2. The FMS7401L must be placed in a special programming mode of operation in order to have full write and read access of all of the device memories. Refer to the
3. Refer to the the
4. Refer to the
5. The Initialization Register 2 shadow register will automatically be restored with its original factory setting during a system reset.
6. Once the read and/or write protection is enabled, the only possible external action of accessing the memory in programming mode is to issue a “Program Erase”
7. The register can only be read.
8. The register cannot be access during normal operation only in programming mode.
9. All SR bits except for bit 7 (the global interrupt mask) are read only when using direct, indirect, or indexed instructions. Software cannot restore SR using the tradi-
10.A) Names in all capital letters are predefined in the assembler. B) Names of the individual bits are not predefined and must be definced using an EQU statement
