Memory map of MB90560/565 series
Notes : • When specified in the ROM mirror function register, the upper part of 00 bank (“004000H to 00FFFFH”)
contains a mirror of the data in the upper part of FF bank (“FF4000H to FFFFFFH”) .
• See “10. ROM Mirror Function Selection Module” in the Peripheral Functions section for details of the
ROM mirror function settings.
Remarks : • The ROM mirror function is provided so the C compiler’s small memory model can be used.
• The lower 16 bits of the FF bank and 00 bank addresses are the same. However, as the FF bank ROM
area exceeds 48 KBytes, the entire ROM data area cannot be mirrored in 00 bank.
• When using the C compiler’s small memory model, locating data tables in the area “FF4000H to
FFFFFFH” makes the image of the data visible in the “004000H to 00FFFFH” area. This means that
data tables located in ROM can be referenced without needing to declare far pointers.
