A-D0 Converter : Input on external pin TIN16
Underflow of TOM0_6 timer
Enable event on TOM0_0-7 (Note 2)
Completion of A-D1 conversion
A-D1 Converter : Input on external pin TIN16
Underflow of TOM0_6 timer
Underflow of TOM1_6 timer
Completion of A-D0 conversion
Note 1: The rated value of conversion accuracy here is that of the microcomputer's own as a single
unit which can be exhibited when the microcomputer is used in an environment where it may
not be affected by the power supply wiring or noise on the board.
Note 2: There are following sources of enable event on TOM0_0-7 (for details, see Chapter 10, "Input/
output Timers"):
•
TID0 overflow/underflow
•
TOM0_7 underflow
•
Input on external pin TIN18
•
TID1 overflow/underflow or TOM1_7 underflow
