(1) Reading the timer Bi register while a count is in progress allows reading , with arbitrary timing, the
(1) If changing the measurement mode select bit is set after a count is started, the timer Bi interrupt
(2) When the first effective edge is input after a count is started, an indeterminate value is transferred to

(3) When using A-D converter in the one-shot mode and in the single sweep mode
(4) When using A-D converter in the repeat mode and in the repeat sweep mode
(5) The A-D conversion in the sweep mode needs the time as follows; (number of sweep pins + 2 pins)
(6) When operating OSD or operating data slicer using the H

WAIT instruction or from the instruction that sets the every-clock stop bit to “1“ within the instruction
queue are perfected and then the program stops. So put at least four NOPs in succession either to the
WAIT instruction or to the instruction that sets the every-clock stop bit to “1.”
In particular, when the Vref connection bit is changed from “0” to “1”, start A-D conversion after an
A-D conversion time for 1 pin.
