2.7.1 Overview of the A-D converter usage
The A-D converter used in the M16C/62A group operates on a successive conversion basis. The follow-
ing is an overview of the A-D converter usage.
(1) Mode
(2) Operation clock
(3) Conversion time
The A-D converter operates in one of five modes:
(a) One-shot mode
(b) Repetition mode
(c) One-shot sweep mode
(d) Repeated sweep mode 0
(e) Repeated sweep mode 1
The operation clock in 5 V operation can be selected from the following: f
divide-by-4 f
equal to that of the CPU’s main clock.
Number of conversion for A-D convertor varies depending on resolution as given. Table 2.7.1 shows
relation between the A-D converter operation clock and conversion time.
Sample & Hold function selected:
No Sample & Hold function:
Carries out A-D conversion on input level of one specified pin only once.
Repeatedly carries out A-D conversion on input level of one specified pin.
Carries out A-D conversion on input level of two or more specified pins only once.
Repeatedly carries out A-D conversion on input level of two or more pins.
Repeatedly carries out A-D conversion on input level of two or more pins. This mode is different from
the repeated sweep mode 0 in that weights can be assigned to specifing pins control the number of
conversion times.
