SCLK/TCLK Divide-by-16 Select
(D0). This bit of the
SMR controls a divide-by-16 prescaler of SCLK/TCLK.
The purpose of this control is to selectively reduce device
power consumption during normal processor execution
(SCLK control) and/or HALT mode (where TCLK sources
counter/timers and interrupt logic).
External Clock Divide-by-Two
(D1). This bit can elimi-
nate 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 further helps lower EMI (i.e., D7 (PCON) = 0, D1
(SMR) = 1). The default setting is zero.
STOP-Mode Recovery Source
(D2, D3, and D4). These
three bits of the SMR register specify the wake up source
of the STOP-Mode Recovery (Figure 32). Table 12 shows
the SMR source selected with the setting of D2 to D4. P33-
P31 cannot be used to wake up from STOP mode when
programmed as analog inputs. When the STOP-Mode Re-
covery sources are selected in this register then SMR2
register bits D0, D1 must be set to zero.
Note:
If the Port2 pin is configured as an output, this output
level will be read by the SMR circuitry..
