yes, to calibrate the DCO, you use the DCO for the SMCLK, and then use
TimerA with the SMCLK, and setup CCTL2 for a capture selecting ACLK as
the signal to trigger the capture by selecting CCIxB in CCTL2 for the
'1232 part.
CCTL2 = CAP | SCS | CCIS_1 | CM_1; // Capture, rising edge, CCIxB=Aclk
Then see how many
SMCLK ticks occurs in CCR2 for one tick of the ACLK.
I'm a little lost on DCO calibration on the F1232. I'm hoping that in
TACCTL2, setting the CCIxB condition hooks up ACLK internally to the
capture input so I don't have to run ACLK out on a pin and then back in on
P2.3.
Thanks in advance for your help.
