External Memory Bus Enable
0 = Ports 0,1,2 are I/0
1 = Ports 0,1,2 are address and
data bus for external memory
or I/O access
Port 44-47 Edge Sensitive Interrupt Input
Enable
0 = No Edge Interrupt Inputs on P44-47
1 = Edge Interrupt Inputs on P44-47
Serial Interface Bus (SIB) Enable
0 = SIB Disabled
1 = SIB Enabled P64=SCLK, P65=SDAT, P66=CHIN,
P67=CHOUT and enable SIB interrupt
In-Circuit-Emulation (ICE) Enable
0 = RUN = RUN and W65C134S is in normal mode of operation
1 = RUN and all on chip addressed memory or I/O for reads or
writes are output on the data bus (this is the emulation mode of
operation)
Port 50-53 Edge Sensitive Interrupt Input Enable
0 = No EDGE interrupt inputs on P50-53
1 = EDGE interrupt inputs on P50-53
Port 54-57 Edge Sensitive Interrupt Input Enable
0 = No EDGE interrupt inputs on P54-57
1 = EDGE interrupt inputs on P54-57
NMIB, IRQ1B and IRQ2B Input Enable
0 = Pins 40-42 are standard I/O
1 = P40=NMIB, P41=IRQ1B, P42=IRQ2B inputs
External ROM Enable
0 = internal ROM at $F000-FFFF
1 = external ROM at $F000-FFFF
