■ MODE SETTINGS
The FR family uses mode pins (MD2 to MD0) and mode data to set the operation mode.
1.
Mode Pins
The MD2 to MD0 pins specify how the mode vector fetch and reset vector fetch is performed.
Settings other than those shown in the following table are prohibited.
2.
Mode data
The data that is written to the internal mode register (MODR) by the mode vector fetch is called mode data.
After the mode register is set, the device runs in the operating mode specified by this register.
The mode data is set by all of the reset sources. User programs cannot set the mode register.
<Details of mode data description>
[bit 23 to bit 19] Reserved bits
Be sure to set these bits to “00000B”.
Operation is not guaranteed if these bits are set to a value other than “00000B”.
[bit 18] ROMA (Internal Flash/ROM enable bit)
This bit configures whether the internal Flash/ROM area (8 0000H to F FFFFH) is enabled.
