RESET_TRST is held LOW
LOCKED is asserted LOW
SMPTE_BYPASS is asserted LOW in slave mode
In addition to the ERROR_STATUS register, a register called ERROR_MASK (Table 4-12)
is included which allows the Host Interface to select the specific error conditions that
will be detected. 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 'zero' after device reset, thus
enabling 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 a 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.
