SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Rev.1.1
Operation of Functional Blocks
The M3062GF8NFP 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, CRC calculation circuit,
A-D converter, and I/O ports.
The following explains each unit.
Memory
Figure 1.3.1 is a memory map of the M3062GF8NFP. The address space extends the 1M bytes from
address 0000016 to FFFFF16. From FFFFF16 down is ROM. For example, in the M3062GF8NFP, there is
64K bytes of internal ROM from F000016 to FFFFF16. The vector table for fixed interrupts such as the reset
_______
and NMI are mapped to FFFDC16 to FFFFF16. The starting address 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.
From 0040016 up is RAM. For example, in the M3062GF8NFP, 8K bytes of internal RAM is mapped to the
space from 0040016 to 023FF16. In addition to storing data, the RAM also stores the stack used when
calling subroutines and when interrupts are generated.
The SFR area is mapped to 0000016 to 003FF16. This area accommodates the control registers for periph-
eral devices such as I/O ports, A-D converter, serial I/O, and timers, etc. Figures 1.6.1 to 1.6.3 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 FFE0016 to FFFDB16. If the starting addresses of subroutines
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. For example, in the M3062GF8NFP, the following spaces cannot be used.
The space between 0240016 and 03FFF16 (Memory expansion and microprocessor modes)
The space between D000016 and EFFFF16 (Memory expansion mode)
