TMPM330
In Single Boot mode, an SIO channel is used for communications with a programming controller. The
same configuration is applied to a communication format on a programming controller to execute the
on-board programming. Both UART (asynchronous) and I/O Interface (synchronous) modes are
supported. The communication formats are shown below.
• UART communication
Communication channel : SIO channel 0
Serial transfer mode : UART (asynchronous), half -duplex, LSB fast
Data length : 8 bit
Parity bits : None
STOP bits : 1 bit
Baud rate : Arbitrary baud rate
• I/O interface mode
Communication channel : SIO channel 0
Serial transfer mode : I/O interface mode, full -duplex, LSB fast
Synchronization clock (SCLK0) : Input mode
Handshaking signal : PE4 configured as an output mode
Baud rate : Arbitrary baud rate
