skrameRtinU
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, 1: 19.2, 2: 38.4, 3: 57.6, 4:
76.8, 5: 115.2 kbps)
* 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 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 expansion
Bits 8 to 11: For future expansion
Bits 4 to 7: For future expansion
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 expansion
Bits 24 to 27: For future expansion
Bits 20 to 23: For future expansion
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)
* 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.
(SCI Receiving Buffer Size㸻192 bytes) .
