■ MODE SETTING
In the FR family, operation mode is set by the mode setting pins (MD2, MD1, MD0) and the mode register
(MODR) .
1.
Mode pins
They are three pins of MD2, MD1 and MD0, and specify the contents of the mode vector fetch.
Note : In the FR family, external mode vector fetch by multiplex bus is not supported.
2.
Mode register (MODR)
The data that are written in the mode register by mode vector fetch is called mode data.
After the mode register (MODR) is set, it operates in the operation mode set by this register.
The mode register is set by all reset source. And Mode data is not written in by the user program.
Note : Conventionally, the address (0000 07FFH) of the mode register for the FR family holds nothing.
Details of the mode register
[bit7 to bit3] Reserved bits
Be sure to set these bits to “00000B”.
Setting the bits to any value other than “00000B” may result in an unpredictable operation .
[bit2] ROMA (Internal ROM enable bit)
Be sure to set this bit to “1”.
