4.18.5.6.6.7 Handshake repetition
Name:
hssPeriod
hssPeriod_CANIO
When using a software handshake, some applications require periodic repetition of the current status. The repeat
time can be defined in this register in ms for this purpose.
Data type
Value
Description
0
Automatic status repeat disabled
UINT
500 to 10000 Repeat time in ms (default = 5000)
4.18.5.6.6.8 Enable handshake manually
Name:
hshSet
hshSet_CANIO
The two registers "Set" and "Clr" can be used to manually manage the handshake via the application.
These registers can be used to force the output level of the RTS hardware handshake line to remain active.
Information:
Only one hsh register can be configured for controlling the RTS line.
Data type
Value
Description
0
RTS line freely available for other flow control methods (default)
USINT
16
RTS line enabled
4.18.5.6.6.9 Disable handshake manually
Name:
hshClr
hshClr_CANIO
The two registers "Set" and "Clr" can be used to manually manage the handshake via the application.
These registers can be used to force the output level of the RTS hardware handshake line to remain passive.
Information:
Only one hsh register can be configured for controlling the RTS line.
Data type

USINT
16
RTS line disabled
4.18.5.6.6.10 Frame detection
Name:
hshFrm
hshFrm_CANIO
This register is used to generally enable hardware-based frame detection. The RTS line is enabled as long as data
is being sent. This Tx-Framing mode can be used to control external interface converters.
Information:
Only one hsh register can be configured for controlling the RTS line.
Data type
Value
Description
0
