Section 19 Controller Area Network (RCAN-TL1)
Bit 0 — This bit is always ‘0’ as this is a receive-only mailbox. Writing a ‘1’ to this bit position
has no effect and always read back as a ‘0’.
(5)
The RXPR1 and RXPR0 are 16-bit read/conditionally-write registers. The RXPR is a register that
contains the received Data Frames pending flags associated with the configured Receive
Mailboxes. When a CAN Data Frame is successfully stored in a receive mailbox the
corresponding bit is set in the RXPR. The bit may be cleared by writing a ‘1’ to the corresponding
bit position. Writing a ‘0’ has no effect. However, the bit may only be set if the mailbox is
configured by its MBC (Mailbox Configuration) to receive Data Frames. When a RXPR bit is set,
it also sets IRR1 (Data Frame Received Interrupt Flag) if its MBIMR (Mailbox Interrupt Mask
Register) is not set, and the interrupt signal is generated if IMR1 is not set. Please note that these
bits are only set by receiving Data Frames and not by receiving Remote frames.
• RXPR1
Note : * Only when writing a ‘1’ to clear.
Bits 15 to 0 — Configurable receive mailbox locations corresponding to each mailbox position
from 31 to 16 respectively.
