SCLK/TCLK Divide-by-16 Select (D0)
D0 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 pro-
cessor execution (SCLK control) and/or HALT Mode (where TCLK sources inter-
rupt logic). After Stop-Mode Recovery, this bit is set to a 0.
Stop-Mode Recovery Source (D2, D3, and D4)
These three bits of the SMR specify the wake-up source of the STOP recovery
(Figure 48 and Table 23 on page 63).
