To program these bits, write the correct value to the locations shown in Table 2-4 using slave pro-
gramming mode. During normal operation, you can determine the values of these bits by reading
the UPROM SFR (Figure 2-5).
You can verify a UPROM bit to make sure it programmed, but you cannot erase it. For this rea-
son, Intel cannot test the bits before shipment. However, Intel does test the features that the UP-
ROM bits enable, so the only undetectable defects are (unlikely) defects within the UPROM cells
themselves.

INTERNAL PERIPHERALS
The internal peripheral modules provide special functions for a variety of applications. This sec-
tion provides a brief description of the peripherals that differ between the 8XC196L

The UPROM special-function register 1 (USFR1) reflects the status of unerasable, programmable
read-only memory (UPROM) locations. This read-only register reflects the status of two bits that
control the output frequency on CLKOUT.
