(Reference)
Input range Unit Remarks
201 Attribute 1 of SIO
channel 1 opened to
user (mount standard)
28100000H 0H ~
FFFFFFFFH
Bits 28 to 31: Baud rate type (0: 9.6, 1: 19.2, 2: 38.4, 3:
57.6, 4: 76.8, 5: 115.2 kbps)
* If flow control is performed, specify 38.4
kbps or less
Specifying a higher baud rate may
generate an overrun error, etc.
Bits 24 to 27: Data length (7 or 8)
Bits 20 to 23: Stop bit length (1 or 2)
Bits 16 to 19: Parity type (0: None, 1: Odd, 2: Even)
Bits 12 to 15: For future extension
Bits 8 to 11: For future extension
Bits 4 to 7:
For future extension
Bits 0 to 3: Use selection (0: Do not use, 1: Use)
* Used on the application level.
202 Attribute 2 of SIO
channel 1 opened to
user (mount standard)
00000001H 0H ~
FFFFFFFFH
Bits 28 to 31: For future extension
Bits 24 to 27: For future extension
Bits 20 to 23: For future extension
Bits 16 to 19: Character send interval (msec)
Bits 12 to 15: Communication method (0: Full-duplex, 1:
Half-duplex)
Bits 8 to 11: Send operation type in half-duplex
communication
(0: Do not check CTS-ON at send
1: Check CTS-ON at send)
Bits 0 to 7: Minimum receive o send switching delay
in half-duplex communication (msec)
203 Attribute 3 of SIO
channel 1 opened to
user (mount standard)
01118040H 0H ~
FFFFFFFFH
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, specify 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.
