[Precautions When Writing to the MODR]
Before writing to the MODR, be sure to set AMD0 through 5 and determine the bus width in each CS (Chip
Select) area.
The MODR does not have bus width setting bits.
The bus width value set with mode pins MD2 through 0 is enabled before writing to the MODR and the bus width
value set with BW1 and 0 of AMD0 through 5 is enabled after writing to the MODR.
For example, the external reset vector is normally executed with area 0 (the area where CS0 is active) and the
bus width at that time is determined by pins MD 2 through 0. Suppose that the bus width is set to 32 or 16 bits
in MD2 though 0 but no value is specified in AMD 0. If the MODR is written in this state, area 0 then switches
to 8-bit bus mode and operates the bus since the initial bus width in AMD0 is set to 8 bits. This causes a
malfunction.
In order to prevent this type of problem, AMD0 through 5 must always be set before writing to the MODR.
