Memory Map and Registers
0 – No RBLE detected.
TBLE — Transmit Message Buffers Locking Error
This error appears if the host tries to lock more than one transmit message buffer. The CC, in that case,
does not grant access to the buffer through the locking mechanism.
1 – TBLE detected.
0 – No TBLE detected.
FBLE — FIFO Message Buffer Lock Error
This error appears if the host tries to lock a FIFO message buffer not through message buffer 0. The CC,
in that case, does not grant access to the message buffer through the locking mechanism.
1 – FBLE detected.
0 – No FBLE detected.
EFLE — Empty FIFO Lock Error
This error appears if the host tries to lock an empty FIFO. The CC, in that case, does not grant access to
the FIFO through the locking mechanism.
1 – EFLE detected.
0 – No EFLE detected.
BULE — Unlocked Message Buffer Lock Error
This error appears if the host tries to access an unlocked message buffer through any active message buffer.
In that case, the host write operations to an active message buffer are ignored, and read operations return
0’s.
1 – BULE detected.
0 – No BULE detected.
Other Error Indicators:
MDPLE — Maximum Dynamic Payload Length Exceeded Error
This error appears if the payload length written into a dynamic segment transmit message buffer
PayloadLength field is greater than the maximum payload length dynamic configured in the maximum
payload length dynamic register MPLDR (see
Section 3.2.3.3.16, “Maximum Payload Length Dynamic
Register
(MPLDR)”). In that case, the wrong payload length is ignored.
1 – MDPLE detected.
0 – No MDPLE detected.
