For the diversion of MB90340-series software assets
In programming of the MB90360 series, keep the following points in mind for the diversion of
MB90340-series software assets in particular.
• Access to the registers which do not exist in the MB90360 series.
As for the registers and bits which exist in MB90340 series but not in the MB90360 series, do
not access them or ensure that the initial value is set. Setting any other value than the initial
value may cause an abnormal operation in emulation using MB90V340.
• Setting of the external interrupt factor select register (EISSR).
The MB90360 series is not equipped with the external interrupt request input, INT8R, INT9,
INT10, INT11, INT12, INT13, INT14 and INT15.
Enabling unequipped terminals causes a false operation. First set the EISSR and then set
each of the registers when DTP/external interrupt is used.
