• Manufacturer: Fortune Semiconductor Corporation

Rev. 1.3
FS3862 has an 1k x 16bits program memory space and a 6 level depth 12bits Stack Register. The Start
up/Reset Vector is at 0x0000H. When FS3862 is started or its program is reset, the Program Counter will point
to Reset Vector. The Interrupt Vector is at 0x0004H. No matter what ISR is processed, the Program Counter will
point to Interrupt Vector.
CPU has a 10-bit program counter capable of address up to 1k x 16 program memory space. The reset vector is
at 0000H and the interrupt vector is at 0004H.
FS3862 has a 64 byte SRAM for Data Memory. The data memory is partitioned into three parts. The area with
address 00h~07h is reserved for system special registers, such as indirect address, indirect address pointer,
status register, working register, interrupt flag, interrupt control register. The address 08h~1Fh areas are
peripheral special registers, such as I/O ports, timer, ADC, signal conditional network control register, LCD
driver. The address 80h~BFh areas are general data memory.
