Event System Filtering
For transmission, three pulse modulation schemes are available:
For reception, a minimum high-level pulse width for the pulse to be decoded as a logical 0 can
be selected. Shorter pulses will then be discarded and the bit will be decoded to logical 1 as if no
pulse where received.
One IRCOM will be available for use with any USART in the device. The module can only be
used in combination with one USART at a time, thus IRCOM mode must not be set for more
than one USART at a time. This must be ensured in the user software.
The Event System can be used as the receiver input. This enables IRCOM or USART input from
other I/O pins or sources than the corresponding RX pin. If Event System input is enabled, input
from the USART's RX pin is automatically disabled. The Event System has Digital Input Filter
(DIF) on the Event Channels, that can be used for filtering. Refer to
on page
• 3/16 of baud rate period.
• Fixed programmable pulse time based on the Peripheral Clock speed.
• Pulse modulation disabled.
