4.2 Notes on SP150Q Signals
4.2.1 High-Speed UARTs Flow Control Signals
• UART2_CTS: UART2 flow control, Clear-To-Send, active low, of the
SP150Q. To be connected to the RTS of the remote UART device. Provision
a 1 kOhm pull-down on CTS pin when flowcontrol is not used. If it is
connected to an external component (like a RS232 driver), the user should
make sure that this component will present a low level to the SP150Q. See
Figure 4-1.
• UART2_RTS: UART2 flow control, Ready-To-Send, active low, of the
SP150Q. To be connected to the CTS of the remote UART device. See Figure
4-1.
• UART3_CTS: UART3 flow control, Clear-To-Send, active low, of the
SP150Q. To be connected to the RTS of the remote UART device. Provision
a 1 kOhm pull-down on CTS pin when flowcontrol is not used. If it is
connected to an external component (like a RS232 driver), the user should
make sure that this component will present a low level to the SP150Q.

• UART3_RTS: UART3 flow control, Ready-To-Send, active low, of the
SP150Q. To be connected to the CTS of the remote UART device. See Figure
