Initial TX Code
Contains a copy of the high byte of the free running timer, which is captured at the beginning of the
identifier field of the frame on the CAN bus.
Refer to
Length (in bytes) of the RX data stored in offset 0x6 through 0xD of the buffer.This field is written by
the TouCAN module, copied from the DLC (data length code) field of the received frame.
Length (in bytes) of the data to be transmitted, located in offset $6 through 0xD of the buffer. This
field is written by the CPU and is used as the DLC field value. If RTR (remote transmission request)
= 1, the frame is a remote frame and will be transmitted without data field, regardless of the value in
TX length.
This field can store up to eight data bytes for a frame. For RX frames, the data is stored as it is re-
ceived from the bus. For TX frames, the CPU provides the data to be transmitted within the frame.
The CPU controls access to this word entry field (16 bits).
NOT ACTIVE — message buffer is not active.
EMPTY — message buffer is active and empty.
FULL — message buffer is full.
OVERRUN — second frame was received into a full
buffer before the CPU read the first one.
BUSY — message buffer is now being filled with a new
receive frame. This condition will be cleared within 20
cycles.
