Lock Bit Programming. 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.
