Table 21.
When CS3 is active D311..0 are transferred to the corresponding I/O pins configured as
outputs (see DIR register). For the I/O pins configured as inputs the corresponding D311..0
will be written by the values applied to those pins while CS3 is low.

Persistency check register (PCHK-A/B)
Addr=0Ah; reset value=00h
Addr=0Bh; reset value=00h
Two input signal per channel, labelled A and B, are submitted to persistency check.
In dynamic mode (STA=0), A and B inputs of the four channels are sampled on the
multiplexed lines IO0 (pin 13) and IO1 (pin 14).
In static mode (STA=1) persistency check is performed on four pairs of lines, assigned to
each channel according to the table:
