Fig. 1 (1) Memory map of M37905M4C-XXXFP/SP (Single-chip mode)
BASIC FUNCTION BLOCKS
These microcomputers contain the following devices in the single
chip: ROM, RAM, CPU, bus interface unit, and peripheral devices
such as the interrupt control circuit, timers, serial I/O,
A-D converter, D-A converter, I/O ports, clock generating circuit, etc.
MEMORY
Figures 1 (1) through (3) show the memory maps. The address
space is 64 Kbytes from addresses 0
16
through FFFF
16
. This ad-
dress space is called
bank 0
16
.
The internal ROM and RAM are allocated as shown in Figures 1 (1)
through (3).
Addresses FFB4
16
through FFFF
16
contain the RESET and the in-
terrupt vector addresses, and the interrupt vectors are stored there.
For details, refer to the section on interrupts.
Allocated to addresses 0
16
through FF
16
are peripheral devices such
as I/O ports, A-D converter, D-A converter, serial I/O, timers, interrupt
control registers, etc. Figures 2 and 3 show the location of SFRs.
