A/D CONVERTER
The
μ
PD78362A contains a high-speed, high-resolution 10-bit analog-to-digital (A/D) converter (conversion
time 12.6
μ
s at an internal clock frequency of 16 MHz). Successive approximation type is adopted. This
converter is provided with eight analog input lines (ANI0-ANI7) and can perform various operations as the
application requires, in select, scan, and mixed modes.
When A/D conversion ends, an internal interrupt (INTAD) occurs. This interrupt can start a macro service
that executes automatic data transfer through hardware.
