Bit P
P = 0: default.
P = 1: mirrors the column data.
Bit Q
Q = 0: default.
Q = 1: mirrors the row data.

Default is TC1 = 0 and TC2 = 0. Selects the default
temperature coefficient for the internally generated V
(see Table 10).
The ranges for TC are given in Chapter 13.

Reducing current consumption can be achieved by one of
the options given in Table 11.
When V
generated, it is usually more efficient to use the on-chip
generator than an external regulator.
