I2C, SPI, UART/RS-232.
I2C: Trigger at a start/stop condition or user-defined frame with address and/or data values. Also, trigger on missing acknowledge, restart, EEPROM read and 10-bit write.
RS-232/422/485/UART: Trigger on Rx or Tx start bit, stop bit, data content or parity error.
SPI: Trigger on SPI (Serial Peripheral Interface) data pattern during a specific framing period. Supports positive and negative chip select framing as well as clock idle framing. Supports MOSI or MISO (4- channel models) data as half duplex data.
