2.9.10 UART1 H/W flow control
Instrument
HyperTerminal.
Jumper Settings
Set JP1 to select TXD2 or DTR1. Set JP2 to select TXD4 or RIn1.
Set JP3 to select RXD2 or DSR1. Set JP4 to select RXD4 or CDn1.
Test Sequence
1.
Configure UART1 HyperTerminal as hardware flow control and
set it to capture text file. Then start TX test.
2.
Start RX test and then send the text file that captured before by
UART1 HyperTerminal.
3.
Program should compare the TX and RX data.
Note
Only for UART1 test.
2.9.11 UART1 S/W flow control
Instrument
HyperTerminal.
Jumper Settings
Set JP1 to select TXD2 or DTR1. Set JP2 to select TXD4 or RIn1.
Set JP3 to select RXD2 or DSR1. Set JP4 to select RXD4 or CDn1.
Test Sequence
1.
Configure UART1 HyperTerminal as Xon/Xoff mode and set it to
capture text file. Then start TX test.
2.
Start RX test and then send the text file that captured before by
UART1 HyperTerminal.
3.
Program should compare the TX and RX data.
Note
Only for UART1 test.
2.10 I2C
The NUC910 I2C includes two channels, I2C_0 and I2C_1, which is a two-wire, bi-directional
serial bus that provides a simple and efficient method of data exchange between devices. The
I2C standard is a true multi-master bus including collision detection and arbitration that
prevents data corruption if two or more masters attempt to control the bus simultaneously.
