s MODE SETTINGS
The FR family uses mode pins (MD2 to MD0) and a mode register (MODR) to set the operation mode.
1.
Mode Pins
The MD2, MD1, and MD0 pins specify how the mode vector fetch is performed.
Values other than those listed in the table are prohibited.
2.
Mode Register (MODR)
The data written to the mode register at 000F_FFF8H using mode vector fetch is called mode data.
After an operation mode has been set in the mode register (MODR), the device operates in the operation mode.
The mode register is set by any reset source. User programs cannot write data to the mode register.
Note : Conventionally the FR family has nothing at addresses (0000_07FFH) in the mode register.
<Register description>
[bit 7 to bit 3] Reserved bit
Be sure to set this bit to 00000. Operation is not guaranteed when any value other than 00000 is set.
[bit 2] ROMA (internal ROM enable bit)
The ROMA bit is used to set whether to enable the internal F-bus RAM and F-bus ROM areas.
