Unit Remarks
201
Attribute 1 of SIO channel 1
opened to user (standard
mount)
28100001H
0H to
FFFFFFFFH
Bits 28 to 31: Baud rate type
(0: 9.6 kbps, 1: 19.2 kbps,
2: 38.4 kbps, 3: 57.6 kbps,
4: 76.8 kbps, 5: 115.2 kbps)
7.3.2 low control is performed, select 38.4
kbps or below. Use of 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 (standard
mount)
00000001H
0H to
FFFFFFFFH
Bits 28 to 31: For future extension
Bits 24 to 27: Reserved by the system
Bits 20 to 23: Reserved by the system
Bits 16 to 19: Character transmission 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 � Send
switching delay in half-duplex
communication (msec)
203
Attribute 3 of SIO channel 1
opened to user (standard
mount)
01118040H
0H to
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,
select 38.4 kbps or below.
Use of a higher baud rate may
generate an overrun error, etc.
Bits 24 to 27: Xon send selection when send is
enabled after SIO-CPU reset
(0: Do not send, 1: Send)
* Valid only in full-duplex
communication with Xon/Xoff
flow control
Bits 20 to 23: Send enable/disable selection at
port open
(0: Disable, 1: Enable)
* Valid only in full-duplex
communication with Xon/Xoff
flow control.
Bits 16 to 19: Xon/Xoff send selection at port
close
(0:Do not send, 1: Send Xon,
2: Send Xoff)
7.3.3 Valid only in full-duplex communication
with Xon/Xoff flow control.
Bits 8 to 15: Flow control high limit (bytes)
Bits 0 to 7: Flow control low limit (bytes)
* If values are set to a magnitude correlation of
“Flow control low limit � SCI receive buffer size –
Flow control high limit”, both the flow control
high/low limits will be converted to a value
corresponding to one-fourth the SCI receive
buffer size.
