Note 1: The products with Flash memory (86FH46,86FH46A,86FH46B) contain the Flash control register (FLSCR) at 0FFFH
Note 2: The TXD and RXD pins to be used in Serial PROM mode differ between the 86FH46 and the 86FH46A,86FH46B.
Note 3: P21,P22 combine XTIN,XTOUT and port.

(note2)
in the DBR area. The products with mask ROM or OTP and the emulation chip do not have the FLSCR register. In
these devices,therefore, a program that accesses the FLSCR register cannot function properly (executes differently
as in the case of a Flash product).
Take this into consideration in your board design when you replace the product. Details of the function refer to the chap-
ter of the 86FH46,86FH46A,86FH46B data sheet.
