Figure 2-35. HVI Block Diagram
NOTE
An external resistor R
EXT_HVI
must always be connected to the
high-voltage input to protect the device pins from fast transients and to
achieve the specified pin input divider ratios when using the HVI in analog
mode.
Voltages up to V
HVI
can be applied to the HVI pin. Internal voltage dividers scale the input signals down
to logic level. There are two modes, digital and analog, where these signals can be processed.
2.4.8.1
Digital Mode Operation
In digital mode (PTAENL=0) the input buffer is enabled if DIENL=1. The synchronized pin input state
determined at threshold level V
TH_HVI
can be read in register PTIL. An interrupt flag (PIFL) is set on input
transitions if enabled (PIEL=1) and configured for the related edge polarity (PPSL). Wakeup from stop
mode is supported.
