2. Operational Description
2.1 CPU Core Functions
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.
2.1.1 Memory Address Map
The TMP86FH09ANG memory is composed Flash, RAM, DBR(Data buffer register) and SFR(Special
function register). They are all mapped in 64-Kbyte address space. Figure 2-1 shows the TMP86FH09ANG
memory address map.

2.1.2 Program Memory (Flash)
The TMP86FH09ANG has a 16384 bytes (Address C000H to FFFFH) of program memory (Flash ).
2.1.3 Data Memory (RAM)
The TMP86FH09ANG has 512bytes (Address 0040H to 023FH) of internal RAM. The first 192 bytes
(0040H to 00FFH) of the internal RAM are located in the direct area; instructions with shorten operations are
available against such an area.
