Description of Action
This bit can eliminate the oscillator divide-by-
two circuitry. When this bit is 0, the System
Clock (SCLK) and Timer Clock (TCLK) are
equal to the external clock frequency divided by
two. The SCLK/TCLK is equal to the external
clock frequency when this bit is set (D1=1).
Using this bit together with D7 of PCON helps
lower EMI (D7 (PCON) =0, D1 (SMR) =1). The
default setting is zero.
These three bits specify the wake-up source of
the Stop-Mode recovery.
This bit, if High, enables the T
after Stop Mode Recovery. The default
configuration of this bit is 1. If the fast wake up
is selected, the Stop Mode Recovery source is
kept active for at least 5 TpC.
