input qualifier circuitry
An input-qualifier circuitry qualifies the input signal to the CAP1
6, QEP1
4, XINT1/2, ADCSOC and
PDPINTA/B pins in the 240xA devices. (The I/O functions of these pins do not use the input-qualifier circuitry).
The state of the internal input signal will change only after the pin is high/low for 6(12) clock edges. This ensures
that a glitch smaller than 5(11) CLKOUT cycles wide will not change the internal pin input state. The user must
hold the pin high/low for 6(12) cycles to ensure the device will see the level change. Bit 6 of the SCSR2 register
controls whether 6 clock edges (bit 6 = 0) or 12 clock edges (bit 6 = 1) are used to block 5- or 11-cycle glitches.
On the LC2402A, input qualification is for the CAP1, CAP2, CAP3, PDPINTA, and XINT2/ADCSOC pins.
enhanced analog-to-digital converter (ADC) module
A simplified functional block diagram of the ADC module is shown in Figure 12. The ADC module consists of
a 10-bit ADC with a built-in sample-and-hold (S/H) circuit. Functions of the ADC module include:
10-bit ADC core with built-in S/H
16-channel, MUXed inputs
Autosequencing capability provides up to 16 “autoconversions” in a single session. Each conversion can
be programmed to select any 1 of 16 input channels
Sequencer can be operated as two independent 8-state sequencers or as one large 16-state sequencer
(i.e., two cascaded 8-state sequencers)
Sixteen result registers (individually addressable) to store conversion values
The digital value of the input analog voltage is derived by:
Digital Value
1024
Input Analog Voltage
V
REFHI

REFLO
V

Digital Value = 0
Digital Value = 1023

Note:
All fractional values are truncated.
Multiple triggers as sources for the start-of-conversion (SOC) sequence
S/W
software immediate start
EVA
Event manager A (multiple event sources within EVA)
EVB
Event manager B (multiple event sources within EVB)
Ext
External pin (ADCSOC)
Flexible interrupt control allows interrupt request on every end-of-sequence (EOS) or every other EOS
Sequencer can operate in “start/stop” mode, allowing multiple “time-sequenced triggers” to synchronize
conversions
EVA and EVB triggers can operate independently in dual-sequencer mode
Sample-and-hold (S/H) acquisition time window has separate prescale control
NOTE: The calibration and self-test features are not present in 240xA devices.
