Note that a read access to Address 0 resets the Interrupt Register. But
it does not mask new interrupts that arise at the time the host reads the
interrupt register; thus, when the Host reads the interrupt register, each
interrupt is either reset, or set again if a new interrupt occurs.

Reserved
These bits are reserved.
Synchronization Change Interrupt Mask
This bit enables or disables the generation of an interrupt
if one or more aspects of the DTTV demodulator
synchronization have changed. If this bit is 0, the interrupt
is masked; if the bit is 1, the interrupt is enabled. The
initial condition for this bit is 0.
TPS Change Interrupt Mask
This bit enables or disables the generation of the interrupt
for the TPS_INFO_CHANGE bit. If this bit is 0, the
interrupt is masked; if the bit is 1, the interrupt is enabled.
The initial condition for this bit is 0.
