We are interfacing the led driver with SAM controller and sending a UART packet {0x87,0xBF,0x80,0x36,0xB8,0xE4} for configuring SYSCFG register and there after reading SYSCFG register with command {0x4B,0xBF,0x80,0x01,0x86} at 500k baud rate as we have 8 MHz crystal connected to TPS9662 device.As the above is the broadcast message we will not get the acknowledgement.
To configure the phase and width we are sending {0x1E,0x61,0x0,0x6C,0x6C,0x6C,0x53,0x46} and {0x1E,0x61,0x10,0xFF,0xFF,0xFF,0x8B,0x36}. There seems no acknowledgement from the TPS driver.
TPS92662 datasheet mentions to do UART communication reset as "holding the RX input low for a period of at least 12 bit times". Hence we sent two uart bytes as 0 via the MCU, but there was gap of 6us between the two bytes sent. Hence UART communication didnot reset.
Can we connect RX input line to ground for the communication reset or What shall we do to reset the uart communication?
Thanks in Advance,
