Table 5: IDCODES Assigned to XC18V00 Devices
The USERCODE instruction gives access to a 32-bit user
programmable scratch pad typically used to supply informa-
tion about the device’s programmed contents. By using the
USERCODE instruction, a user-programmable identifica-
tion code can be shifted out for examination. This code is
loaded into the USERCODE register during programming of

XC18V00 TAP Characteristics
The XC18V00 family performs both in-system programming
and IEEE 1149.1 boundary-scan (JTAG) testing via a single
4-wire Test Access Port (TAP). This simplifies system
designs and allows standard Automatic Test Equipment to
perform both functions. The AC characteristics of the
XC18V00 TAP are described as follows.

These TAP timing characteristics are identical for both
boundary-scan and ISP operations.
