For Users of the HC11 (or compatible). The
HC11 turns off its E clock when it sleeps. There-
fore, if you are using an HC11 (or compatible) in
your design, and you wish to use the Power-down
mode, you must not connect the E clock to CLKIN
(PD1). You should instead connect a crystal oscil-
lator to CLKIN (PD1). The crystal oscillator fre-
quency must be
less than 15 times the frequency
of AS. The reason for this is that if the frequency is
greater than 15 times the frequency of AS, the
PSD8XXFX keeps going into Power-down mode.
Other Power Saving Options. The PSD8XXFX
offers other reduced power saving options that are
independent of the Power-down mode. Except for
the SRAM Stand-by and PSD Chip Select Input
(CSI, PD2) features, they are enabled by setting
bits in PMMR0 and PMMR2.
