The HC_ERROR interrupt status bit is set when the host requests an illegal mode
transition (as defined in the Section 6.8.1
and Section 6.9.1). It is reset after a successful
read operation on the Interrupt Status register.
TEMP_ERROR: A TEMP_ERROR interrupt signals the presence of an overtemperature
condition.
The TEMP_ERROR interrupt status bit is set when the temperature warning level
(TEMP_WARN = 1) or temperature high level (TEMP_HIGH = 1) is exceeded. It is reset
after the flag (or flags) that triggered the interrupt has been reset and the Interrupt Status
register has been read successfully. Resetting TEMP_ERROR triggers a falling edge on
INTN to indicate to the host that the overtemperature condition is no longer present.
