On mask set B96D and newer, the CONFIG register may only be programmed or
erased while the MCU is operating in the test mode or the bootstrap mode. This inter-
lock was added to help prevent accidental changes to the CONFIG register.
The following program segment demonstrates how to program the CONFIG register.
This program assumes that the CONFIG register was previously erased.
The following program segment demonstrates the erase procedure for the CONFIG
register.
*On entry, A = data to be programmed onto CONFIG
