A-D Converter
(4) Functions selection
(a) Sample & Hold function
(b) 8-bit A-D to 10-bit A-D switching function
(c) A-D conversion by external trigger
(d) External operation amplifier connection function
(e) Expanded analog input pins function
(f) Connecting or cutting Vref
The following are exsamples in which functions (a) through (f) are selected:
• One-shot mode ...................................................................................................................... P2-116
• One-shot mode, trigger by AD
• One-shot mode, software trigger, expanded analog input ..................................................... P2-120
• One-shot mode, software trigger, external operation amplifier connected ............................ P2-122
• Repeat mode, software trigger .............................................................................................. P2-124
• One-shot sweep mode, software trigger ................................................................................ P2-126
• Repeated sweep mode 0, software trigger ............................................................................ P2-128
• Repeated sweep mode 1, software trigger ............................................................................ P2-130
Sample & Hold function samples input voltage when A-D conversion starts and carries out A-D
conversion on the voltage sampled. When A-D conversion starts, input voltage is sampled for 3
cycles of the operation clock. When the Sample & Hold function is selected, set the operation clock
for A-D conversion to 1 MHz or higher.
Either 8-bit resolution or 10-bit resolution can be selected. When 8-bit resolution is selected, the 8
higher-order bits of the 10-bit A-D are subjected to A-D conversion. The equations for 10-bit resolu-
tion and 8-bit resolution are given below:
The user can select software or an external pin input to start A-D conversion.
The selected A-D convertor pin input voltage can be output from the ANEX0 pin. By connecting an
operation amplifier between the ANEX1 pin and ANEX0 pin when using this function, the input volt-
age to all A-D conversion pins can be amplified with one operation amplifier.
A-D conversion can be done for voltage input from either the ANEX0 pin or the ANEX1 pin.
Cutting Vref allows decrease of the current flowing into the A-D converter. To decrease the
microcomputer's power consumption, cut Vref. To carry out A-D conversion, start A-D conversion 1
s or longer after connecting Vref.
