PIC32MK1024MCF100 CAN4 registers

The 97 registers of CAN4 (CAN 4), from 0xBF885000, with their reset value and every field. The PIC32MK1024MCF100 has 1917 registers in 121 peripherals, one page each.

Most PIC32 SFRs have three more registers right after them: CLR at +4, SET at +8 and INV at +C (T1CONCLR, T1CONSET, T1CONINV), which clear, set or flip just the bits written as 1, in one write.

Field	Bits	What it does
FSIZE	20:16	FIFO Size bits `0` FIFO is 1 message deep `1` FIFO is 2 messages deep `2` FIFO is 3 messages deep `31` FIFO is 32 messages deep
FRESET	14	FIFO Reset bits `0` No effect `1` FIFO will be reset when bit is set, cleared by hardware when FIFO is reset. After setting, the user application should poll whether this bit is clear before taking any action
UINC	13	Increment Head/Tail bit `0` 1: (FIFO configured as a Transmit FIFO) When this bit is set, the FIFO head will increment by a single message `0` 0: (FIFO configured as a Receive FIFO) When this bit is set, the FIFO tail will increment by a single message
DONLY	12	Store Message Data Only bit `0` 1: (FIFO configured as a Transmit FIFO) This bit is not used and has no effect. `0` 0: (FIFO configured as a Receive FIFO) 1 = Only data bytes will be stored in the FIFO, 0 = Full message is stored, including identifier
TXEN	7	TX/RX Buffer Selection bit `0` FIFO is a Receive FIFO `1` FIFO is a Transmit FIFO
TXABAT	6	Message Aborted bit `0` Message completed successfully `1` Message was aborted
TXLARB	5	Message Lost Arbitration bit `0` Message did not lose arbitration while being sent `1` Message lost arbitration while being sent
TXERR	4	Error Detected During Transmission bit `0` A bus error did not occur while the message was being sent `1` A bus error occurred while the message was being sent
TXREQ	3	Message Send Request `0` 1: (FIFO configured as a Transmit FIFO) Setting this bit to 1 requests sending a message. The bit will automatically clear when all the messages queued in the FIFO are successfully sent. Clearing the bit to 0 while set will request a message abort. `0` 0: (FIFO configured as a Receive FIFO) This bit has no effect.
RTREN	2	Auto RTR Enable bit `0` When a remote transmit is received, TXREQ will be unaffected `1` When a remote transmit is received, TXREQ will be set
TXPRI	1:0	Message Transmit Priority bits `0` Lowest Message Priority `1` Low Intermediate Message Priority `2` High Intermediate Message Priority `3` Highest Message Priority
