2. Operational Description
2.1 CPU Core Functions
2.1.1 Memory Address Map
2.1.2 Program Memory (MaskROM)
2.1.3 Data Memory (RAM)
The CPU core consists of a CPU, a system clock controller, and an interrupt controller.
This section provides a description of the CPU core, the program memory, the data memory, and the reset circuit.

(0040H to 00FFH) of the internal RAM are located in the direct area; instructions with shorten operations are
available against such an area.
should be initialized by an initialization routine.
The TMP86C408IDMG memory is composed MaskROM, RAM and SFR(Special function register). They
The TMP86C408IDMG has a 4096 bytes (Address F000H to FFFFH) of program memory (MaskROM ).
The TMP86C408IDMG has 256bytes (Address 0040H to 013FH) of internal RAM. The first 192 bytes
The data memory contents become unstable when the power supply is turned on; therefore, the data memory
