AS7265x − Detailed Description
UART Command Interface
If selected by the I2C_ENB pin setting, the UART module imple-
ments the TX and RX signals as defined in the RS-232 / V.24
standard communication protocol. Serial flash EPROM is a re-
quired operating companion device to enable the UART com-
mand interface.

UART Feature List
• Full duplex operation (independent serial receive and
transmit registers).
• Factory set to 115.2k Baud
• Supports serial frames with 8 Data Bits, no Parity and 1
Stop Bit.
Operation
Transmission
If data is available in the transmit FIFO, it will be moved into the
output shift register and the data will be transmitted at the
configured Baud Rate, starting with a Start Bit (logic zero) and
followed by a Stop Bit (logic one).
Reception
At any time, with the receiver being idle, if a falling edge of a
start bit is detected on the input, a byte will be received and
stored in the receive FIFO. The following Stop Bit will be checked
to be logic one.
