7.6 A/D Converter
An analog-to-digital (A/D) converter with eight multiplexed inputs (ANI0 through ANI7) is provided.
This A/D converter is of successive approximation type. The result of conversion is retained by an 8-bit A/D
conversion result register (ADCR). Therefore, high-speed, high-accuracy conversion can be performed (conversion
time: approx. 7.5
μ
s at f
CLK
= 16 MHz).
A/D conversion can be started in either of the following two modes:
Hardware start: Conversion is started by trigger input (INTP5).
Software start: Conversion is started by setting a bit of the A/D converter mode register (ADM).
After started, the A/D converter operates in the following modes:
Scan mode: Two or more analog inputs are sequentially selected, and data to be converted are obtained from
all the input pins.
Select mode: Only one analog input pin is used to continuously obtain converted values.
These operation modes and whether starting or stopping the A/D converter are specified by the ADM.
When the result of conversion is transferred to the ADCR, interrupt request INTAD is generated. By using this
request and macro service, the converted values can be successively transferred to the memory.
