7.29 User configuration bytes
7.30 User sector security bytes
Some user-configurable features of the P89LPC932A1 must be defined at power-up and
therefore cannot be set by the program after start of execution. These features are
configured through the use of the flash byte UCFG1. Please see the P89LPC932A1 User
manual for additional details.
There are eight User Sector Security Bytes on the P89LPC932A1 device. Each byte
corresponds to one sector. Please see the P89LPC932A1 User manual for additional
details.
