10 8-Bit Microcontroller Core
The FMS7401/7401L’s 8-bit microcontroller core is specifically designed for low cost applications involving bit manipulation,
shifting and block encryption. It is based on a modified Harvard architecture meaning peripheral, I/O and RAM locations are
addressed separately from instruction data.
The core differs from the traditional Harvard architecture by aligning the data and instruction memory sequentially. This
allows the X-pointer (11-bits) to point to any memory location in either segment of the memory map. This modification
improves the overall code efficiency of the microcontroller core and takes advantage of the flexibility found on the von Neu-
mann architecture and stored program concept.
10.1 Core Registers
The microcontroller core has five general-purpose registers. These registers are the Accumulator (A), X-Pointer (X), Program
Counter (PC), Stack Pointer (SP) and Status Register (SR). The X, SP and SR registers are memory mapped while A and PC
are not.
