WI.DP1205-XXX-R DATASHEET
5. Data Operation Modes
The XE1205 is user-programmable between two modes of operation:
Continuous Mode: each bit transmitted or received is accessed directly at the DATA input/output pin.
Buffered Mode: a 16-byte FIFO is used to store each data byte transmitted or received. This data is written
to/read from the FIFO via the SPI bus. It reduces processor overhead and reduces connections (the DATA
input/output pin is not used in this operation mode)
In receiver mode, two lines are dedicated to interrupt information. The interrupt pins are IRQ0 and IRQ1. IRQ0
has 3 selectable sources. IRQ1 has 2 selectable sources. The two following tables summarize the interrupt
management.
Table 4, IRQ0 Interrupt Sources in Receive Mode
Table 5, IRQ1 Interrupt Sources in Receive Mode
For more information about the data operation modes, please refer to the XE1205 datasheet chapter:
