(Ordering Information at the end of the Datasheet
DESCRIPTION
The use of the CMFP in a system can significantly
reduce chip count, thereby reducing system cost.
TheCMFPiscompletely68000 bus compatible,and
24 directly addressable internal registers provide
thenecessary control andstatus interfacetothepro-
grammer.
TheCMFP isa derivative of theMK3801 STI,aZ80
family peripheral.
