UCD9080
SLVS692E – SEPTEMBER 2006 – REVISED MAY 2008 ................................................................................................................................................... www.ti.com
Error conditions are logged by the UCD9080 and are accessible to the user via reading the ERROR register.
This is a 6-byte register with the following format:
Error conditions encountered during processing post error logs to this register with some exceptions. This
register is internally managed as a FIFO (with a depth of 8). Errors are posted to the FIFO as they occur, and
read out of the FIFO via I
2
C access. Due to the unknown latency of host extraction of the FIFO data, the
UCD9080 only posts to the FIFO if there is room to write. There is no real-time impact to processing in the
UCD9080 if this FIFO is full and cannot be posted to.
The values in registers 0x22 through 0x25 are reset to a value of 0 during UCD9080 RESET.
