■ CPU CORE
Memory space
The MB89550A has 64 Kbytes of memory space, composed of the I/O area, RAM area, ROM area, and external
area. The memory space includes general purpose registers, as well as areas used for special purposes such
as vector tables.
I/O Area (address : 0000H to 007FH)
This area is allocated to control registers and data registers for internal peripheral functions.
Because the I/O area is part of memory space, it can be accessed in the same ways. Direct addressing provides
faster access.
RAM Area
Static RAM is provided for use as an internal data area.
The size of internal RAM differs between product models.
High speed access is available to addresses 80H to FFH using direct addressing (the area available for use is
restricted on some models).
Addresses 100H to 1FFH are used as the general-purpose register area.
If a reset is applied during writing to RAM, the value of date at the target addresses is not assured.
ROM Area
ROM is provided for use as the internal program area.
The size of internal ROM differs between product models.
Addresses FFC0H to FFFFH are used for special purpose data such as vector tables.
