SETTING MODE
In the FR family, the mode pins (MD2, MD1, MD0) and the mode register (MODR) are used to set the operating
mode.
1.
Mode Pins
The three pins MD2, MD1, MD0 are used in mode vector fetch instructions, and also to make settings in test mode.

2.
Mode Register (MODR)
The mode data fetch instruction writes data to the address “0000_07FD
H
” called the mode data.
The area “0000_07FD
H
” is the mode register (MODR). When a setting is made to this register, the device will
operate the mode corresponding to that setting.
The mode register can only be set by a reset source at the INIT level. It is not possible to write to this register
from a user program.
No data exists at the FR family mode register address (0000_07FF
H
).
[bit7-3] Reserved bits
These bits should always be set to “00000.” If set to any other value, stable operation is not assured.
[bit2] ROMA (Internal RAM enable bit)
This bit indicates whether internal RAM is enabled.
ROMA
[bit1, 0] WTH1, WTH0 (Bus width indicator bits)
In external bus mode, these bits determine the bus width setting.
In external bus mode, the value of these bits sets the BW1, 0 bits in the AMD0 register (CS0 area).
