Operation mode
Bus mode
Bus mode indicates the mode that controls the internal ROM operations and external access function operations,
and specifies using the mode set up terminals (MD2, MD1 and MD0) and ROMA bit contents within the mode data.
Access mode
Access mode indicates the mode that controls the external data bus width, and specifies by the WTH1/WTH0
bits within the mode data, and the DBW1/DBW0 bits within ACR0 to ACR3 (Area Configuration Registers) .
Bus mode
In the FR60 Lite, there are 3 bus modes shown next.
Refer to “s MEMORY SPACE” for details.
Bus mode 0 (single chip mode)
This mode enables access to internal I/O, external RAM, and to internal ROM while disabling access to any
other area.
The external pin functions as a peripheral function or a general purpose port.
The pin does not work as a bus pin.
Bus mode 1 (Internal ROM external bus mode)
Not supported by this model.
This mode enables access to internal I/O, internal RAM, and to internal ROM, in which access to externally
accessible areas are handled as access to external space.
A part of an external pin functions as a bus pin.
Bus mode 2 (external ROM external bus mode)
Not supported by this model.
This mode enables access to internal I/O and internal RAM while disabling access to internal ROM, in which
access to externally accessible areas or internal ROM space are handled as access to external space.
A part of an external functions as a bus pin.
