An example sequence of commands and data is shown in
Table 25. In this example the shift register is filled with the
following data: MMVPR = 11010000, and the seal bit
is logic 0.
It is assumed that the OM6208 has just been reset. After
transmitting the last bit, the OM6208 can exit or remain in
CALMM mode (see step 1). Note that while in CALMM

Note
1. The data for the bits is not in the correct shift register position until all bits have been sent.

mode the interface does not recognize commands in the
normal sense.
After this sequence has been applied it is possible to
observe the impact of the data shifted in. The sequence
described is not useful for OTP programming because the
number of bits with the value logic 1’ is greater than that
allowed for programming (see Section 17.7). The shift
register contents after this action are shown in Fig.44.
