The 181 registers of CAN2 (CAN 2), from 0xBF881000, with their reset value and every field. The PIC32MZ1064DAG176 has 2308 registers in 102 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.

31 FIFO is 32 messages deep
FRESET

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

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

Store Message Data Only bit(1)
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

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 (1) will request a message abort.
0 0: (FIFO configured as a Receive FIFO) This bit has no effect.
