2. OPERATION OF FUNCTIONAL BLOCKS
2.1 Memory
This microcomputer accommodates certain units in a single chip. These units include ROM and RAM to
store instructions and data and the central processing unit (CPU) to execute arithmetic/logic operations.
Also included are peripheral units such as timers, serial I/O, D-A converter, DMAC, OSD circuit, data slicer,
A-D converter, and I/O ports.
The following explains each unit.
Figure 2.1.1 is a memory map. The address space extends the 1M bytes from address 00000
FFFFF
The vector table for fixed interrupts such as the reset mapped to FFFDC
dress of the interrupt routine is stored here. The address of the vector table for timer interrupts, etc., can be
set as desired using the internal register (INTB). See the section on interrupts for details.
5K bytes of internal RAM is mapped to the space from 02C00
RAM also stores the stack used when calling subroutines and when interrupts are generated.
The SFR area is mapped to 00000
eral devices such as I/O ports, A-D converter, serial I/O, and timers, etc. Figures 2.1.2 to 2.1.5 are location
of peripheral unit control registers. Any part of the SFR area that is not occupied is reserved and cannot be
used for other purposes.
The special page vector table is mapped to FFE00
or the destination addresses of jumps are stored here, subroutine call instructions and jump instructions
can be used as 2-byte instructions, reducing the number of program steps.
In memory expansion mode and microprocessor mode, a part of the spaces are reserved and cannot be
used. The following spaces cannot be used.
• The space between 01000
• The space between B0000
