Description of functions
4.4.3.2 Number of databits (Databits)
This parameter defines whether the data are transmitted with a length of 7 or 8
bits. (e.g. databits = 8)
4.4.3.3 Parity (Parity)
Parity defines whether a parity bit is to be transmitted at the same time. The pos-
sibilities are even parity (even), odd parity (odd) or no parity (no) (e.g. Parity =
no).
4.4.3.4 Flow control (Handshake)
The handshake parameter defines the type of flow control of the serial data
transmission. Possible settings are no handshake (no), software handshake (soft-
ware) or hardware handshake (hardware) (e.g. Handshake = no).
4.4.4 CANlink settings [CANlink]
4.4.4.1 Baudrate (CANbaudrate)
There are two possibilities for setting the baudrate:
1. Setting a CiA baudrate:
10 kbit/s, 20 kbit/s, 50 kbit/s, 100 kbit/s, 125 kbit/s, 250 kbit/s, 800 kbit/s
and 1000 kbit/s can be set (e.g. CANbaudrate=1000).
2. Setting via bit timing register
The baudrate can be set via the bit timing registers BTR0 and BTR1 of the
controller. Baudrates can thus also be selected that are not listed in the ta-
ble.
The values for the bit timing registers BTR0 and BTR1 are determined ac-
cording to the specifications for the Philips CAN controller SJA1000 with
16 MHz clock frequency (see data sheet SJA1000).
However, prescaler PSC (bits 0..5 of the BTR0) must not be larger than
0x1F, with the exception of baudrate 10 kbit, which can be set via
0x31/0x1C.
(e.g. CAN baudrate = 0x04/0x14 for 200 kbit/s).
4.4.4.2 Frame format (FrameFormat)
The frame format states in which format the messages are transmitted on the
CAN bus. Standard frames (11 bit identifiers) or extended frames (29 bit identifi-
ers) can be selected.
(e.g. FrameFormat = std)
