Bits 28 to 31:
Flow control type
(0: None, 1: Xon/Xoff, 2: Hardware)
* Valid only in full-duplex communication.
* If flow control is performed, select 38.4 kbps or less. Specifying a higher baud rate
may generate an overrun error, etc.
Bits 24 to 27:
Xon send selection when send after SIO-CPU reset is enabled
(0: Do not send, 1: Send)
* Valid only in full-duplex communication with Xon/Xoff flow control.
Bits 20 to 23:
Send enable selection when the port is open
(0: Disable, 1: Enable)
* Valid only in full-duplex communication with Xon/Xoff flow control.
Bits 16 to 19:
Xon/Xoff send selection when the port is closed
(0: Do not send, 1: Send Xon, 2: Send Xoff)
* Valid only in full-duplex communication with Xon/Xoff flow control.
Bits 8 to 15:
Flow control high limit (byte)
Bits 0 to 7:
Flow control low limit (byte)
* If the specified value satisfies the condition “Flow control low limit
t SCI receive
buffer size – flow control high limit,” both the flow control high limit and low limit will
be replaced by values corresponding to 1/4 of the SCI receive buffer size before the
applicable processing is performed.
