PIN DESCRIPTIONS
The basic functions of each pin of the ML63512A/63514A are described in Table 1.
A symbol with a slash (/) denotes a pin that has a secondary function.
Refer to Table 2 for secondary functions.
Fortype, "—"denotesapowersupplypin, "I"aninputpin, "O"anoutputpin, and"I/O"aninput-
output pin.
For pin, "TB" denotes a 48-pin flat package (48TQFP), and "TP" a 64-pin flat package (64TQFP).
