The pulse sequences consist of the following groups of pulses:
1. An enable sequence.
2. A bitfield address sequence.
3. When permanently setting the bitfield, a long V
PH
fuse-blow-
ing pulse. (Note: Blown bit fuses cannot be reset.) When
provisionally trying a value, a short V
PH
pulse.
4. When permanently setting the bitfield, the level of V
CC
must
be allowed to drop to zero between each pulse sequence, in
order to clear all registers. However, when provisionally set-
ting bitfields, V
CC
must be maintained at V
PL
between pulse
sequences, in order to maintain the prior bitfield settings while
preparing to set additional bitfields.
Bitfields that are not set are evaluated as zeros. The bitfield-level
fuses for 0 value bitfields are never blown. This prevents inad-
vertently setting the bitfield to 1. Instead, blowing the device-
level fuse protects the 0 bitfields from being accidentally set in
the future.
Two pulse sequences for provisionally trying the calibration
value 5 are shown in figure 2. Because the bitfields must be set
individually, 5
10
must be programmed as binary 101. Bit 3 is
set to 1 (000100
2
, which is 4
10
), then bit 1 is set to 1 (000001
2
,
which is 1
10
). Bit 2 is ignored, and so remains 0.
Two pulse sequences for permanently setting the calibration
value 5 are shown in figure 3. The final V
PH
pulse, which was
used as a short delimiter when trying values, is maintained for a
longer period, enough to blow the corresponding bitfield-level
fuse.
