All bits, with the exception of the LOCK_ERR, will also be cleared if a change in the
video standard is detected, or under the following conditions:
The whole ERROR_STATUS register, including the LOCK_ERR bit, will be set
LOW during a system reset (RESET = LOW).
LOCKED is asserted LOW
SMPTE_BYPASS is asserted LOW in Manual mode
In addition to the ERROR_STATUS register, a register called ERROR_MASK is
included to select the specific error conditions that will be detected (
Table 3-12
).
There is one bit in the ERROR_MASK register for each type of error represented
in the ERROR_STATUS register.
The bits of the ERROR_MASK register will default to '0' after a device reset, thus
allowing all error types to be detected. The host interface may disable individual
error detection by setting the corresponding bit HIGH in this register.
Error conditions are also indicated to the application layer via the status signal pin
DATA_ERROR. This output pin is an inverted logical 'OR'ing of each error status
flag stored in the ERROR_STATUS register. DATA_ERROR is normally HIGH, but
will be set LOW by the device when an error condition that has not been masked
is detected.

VD_STD_ERR
Video Standard Error Flag. Set HIGH when a
mismatch between the received SMPTE 352M
packets (version 1 or version 0) and the
calculated video standard occurs.
R
0
5
FF_CRC_ERR
Full Field CRC Error Flag. Set HIGH when a Full
Field (FF) CRC mismatch has been detected in
Field 1 or 2

AP_CRC_ERR
Active Picture CRC Error Flag. Set HIGH when an
Active Picture (AP) CRC mismatch has been
detected in Field 1 or 2.
R
0
3
LOCK_ERR
Lock Error Flag. Set HIGH whenever the
LOCKED pin is LOW (indicating the device is not
correctly locked).

data packet checksum error has been detected.
