Preliminary data sheet
8.2 Features
The ADC consists of an 8-input multiplexer which feeds a sample-and-hold circuit
providing an input signal to comparator inputs. The control logic in combination with the
SAR drives a digital-to-analog converter which provides the other input to the comparator.
The output of the comparator is fed to the SAR.
10-bit, 8-channel multiplexed input, successive approximation ADCs. (10-bit,
4-channel on P89LPC983)
Eight result register pairs.
Six operating modes:
Three conversion start modes:
10-bit conversion time of 4 μs at an A/D clock of 9.0 MHz.
Interrupt or polled operation.
Boundary limits interrupt.
Clock divider.
Power-down mode.
Fixed channel, single conversion mode.
Fixed channel, continuous conversion mode.
Auto scan, single conversion mode.
Auto scan, continuous conversion mode.
Dual channel, continuous conversion mode.
Single step mode.
Timer triggered start.
Start immediately.
Edge triggered.
