11.2.2
When chip select is active and a write strobe occurs
(PMCSx = 1 and PMWR = 1), the data from PMD<7:0>
is captured into the lower PMDIN1L register. The
PMPIF and IBF flag bits are set when the write
ends.The timing for the control signals in Write mode is
displayed in Figure 11-3. The polarity of the control
signals are configurable.

11.2.3
When chip select is active and a read strobe occurs
(PMCSx = 1 and PMRD = 1), the data from the
PMDOUT1L register (PMDOUT1L<7:0>) is presented
on to PMD<7:0>. Figure 11-4 provides the timing for
the control signals in Read mode.
