The MAXQ610 User’s Guide contains all the informa-
tion that is needed to develop application code for the
MAXQ613 microcontroller. However, even though the
MAXQ610 and the MAXQ613 are largely code-com-
patible, there are certain differences between the two
devices that must be kept in mind when referring to the
MAXQ610 User’s Guide.
The following registers on the MAXQ610 (which are
described in the MAXQ610 User’s Guide) do not exist
on the MAXQ613, and all references to them should be
disregarded:
• Port 3 Output Register (PO3)
• Port 3 Direction Register (PD3)
• Port 3 Input Register (PI3)
• Port 4 Output Register (PO4)
• Port 4 Direction Register (PD4)
• Port 4 Input Register (PI4)
