After the desired B

calibration value
is programmed, and all of the corresponding bitfield-level fuses
are blown, the device-level fuse should be blown. To do so, the
lock bit (bitfield address 32) should be encoded as 1 and have
its fuse blown. This is done in the same manner as permanently
setting the other bitfields, as shown in figure 9.

Enabling Addressing Mode
.
The first segment of code is a
keying sequence used to enable the bitfield addressing mode. As
shown in figure 7, this segment consists of one short V
PH
pulse,
one V
PM
pulse, and one short V
PH
pulse, with no supply inter-
ruptions. This sequence is designed to prevent the device from
being programmed accidentally, such as by noise on the supply
line.
Address Selection
.
After addressing mode is enabled, the
target bitfield address, is indicated by a series of V
PM
pulses, as
shown in figure 8.
