The TXnRTS pins are input pins that can be configured
as:
• Request-to-send inputs, which provide an
• Standard digital inputs
Configuration and control of these pins is accomplished
using the TXRTSCTRL register (see Register 3-3). The
TXRTSCTRL register can only be modified when the
MCP2515 is in Configuration mode (see Section 10.0
“Modes of Operation”). If configured to operate as a
request-to-send pin, the pin is mapped into the
respective TXBnCTRL.TXREQ bit for the transmit
buffer. The TXREQ bit is latched by the falling edge of
the TXnRTS pin. The TXnRTS pins are designed to
allow them to be tied directly to the RXnBF pins to
automatically initiate a message transmission when the
RXnBF pin goes low.
The TXnRTS pins have internal pull-up resistors of
100 kΩ (nominal).

The MCU can request to abort a message in a specific
message
TXBnCTRL.TXREQ bit.
In addition, all pending messages can be requested to
be aborted by setting the CANCTRL.ABAT bit. This bit
MUST be reset (typically after the TXREQ bits have
been verified to be cleared) to continue transmitting
messages. The TXBnCTRL.ABTF flag will only be set
if the abort was requested via the CANCTRL.ABAT bit.
Aborting a message by resetting the TXREQ bit does
NOT cause the ABTF bit to be set.
