Product data sheet
6.14 User configuration bytes
6.15 UCFG
Table 37.
This device contains some non-volatile bytes which allow the user to configure the device.
These bytes are programmed or read using the configuration read or write command
(CONF) with a programmer that supports ICP. The user configuration bytes, their CONF
address are shown in
Table 38.
The user configuration bits in the UCFG register allow the user to configure some of the
operating characteristics of the device and are shown in
Table 39.
