A-D ConverterMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER2.7 A-D Converter2.7.1 OverviewThe A-D converter used in the M16C/62 group operates on a successive conversion basis. The followingis an overview of the A-D converter.(1) ModeThe A-D converter operates in one of five modes:(a) One-shot modeCarries out A-D conversion on input level of one specified pin only once.(b) Repetition modeRepeatedly carries out A-D conversion on input level of one specified pin.(c) One-shot sweep modeCarries out A-D conversion on input level of two or more specified pins only once.(d) Repeated sweep mode 0Repeatedly carries out A-D conversion on input level of two or more pins.(e) Repeated sweep mode 1Repeatedly carries out A-D conversion on input level of two or more pins. This mode is different fromthe repeated sweep mode 0 in that weights can be assigned to specifing pins control the number ofconversion times.(2) Operation clockThe operation clock in 5 V operation can be selected from the following: fAD, divide-by-2 fAD, anddivide-by-4 fAD. In 3 V operation, the selection is divide-by-2 fAD or divide-by-4. The fAD frequency isequal to that of the CPU’s main clock.(3) Conversion timeNumber of conversion for A-D convertor varies depending on resolution as given. Table 2.7.1 showsrelation between the A-D converter operation clock and conversion time.Sample & Hold function selected:33 φAD cycles for 10-bit resolution, or 28 φAD cycles for 8-bit resolutionNo Sample & Hold function:59 φAD cycles for 10-bit resolution, or 49 φAD cycles for 8-bit resolutionTable 2.7.1.
