NOTE A: VIS_OE will be visible at pin 97 of LF2407A when ENA_144 is high along with BVIS bits (10,9 of WSGR register − FFFFh@I/O) set to

10 or 11. CLKOUT and VIS_OE indicate internal memory write cycles (program/data). During VIS_OE cycles, the external bus will be

driven. CLKOUT is to be used along with VIS_OE for trace capabilities.
