Configuration Window
TXRTSCTRL , BFPCTRL , CANINTF , CANINTE and CANCTRL are all modified from this
window. These are the control and flag registers for the MCP2515.
4.3.4.1
TXRTSCTRL
This register configures the RTS pins (TXnRTS) as either request-to-send or as digital
inputs. The pin values are displayed in the register if configured as digital inputs.
4.3.4.2
BFPCTRL
This register configures the receive buffer full pins (RXnBF) as buffer full interrupts or
digital outputs. The value of the pins are displayed if configured as digital outputs.
4.3.4.3
CANINTF
CANINTF is the flag register for the eight sources of interrupts.
4.3.4.4
CANINTE
This register is the interrupt-enable for the eight interrupt sources. Enabled interrupts
are mapped to the INT pin.
4.3.4.5
CANCTRL
CANCTRL sets the modes of operation and the clock out enable and prescaler
(CLKOUT pin).
