ECO_TR
External Crystal Oscillator Trim Register
This register sets the adjustment for the 32.768 kHz External Crystal Oscillator.
The value in this register should not be changed.
The value is used to trim the 32.768 kHz external crystal oscillator and
is set to the device specific,
best value during boot. In the table above, note that reserved bits are grayed table cells and are
not described in the bit description section below. Reserved bits should always be written with a value of ‘0’. For additional
information, refer to the
“Register Definitions” on page 23
in the External Crystal Oscillator (ECO) chapter.
7:6
PSSDC[1:0]
Sleep duty cycle. Controls the ratios (in numbers of 32.768 kHz clock periods) of “on” time versus
“off” time for PORLVD, Bandgap reference, and pspump.
These bits should not be changed.
