A program counter watchdog is used when the core performs
block processing (which can span several samples). The watchdog
flags an error if the program counter reaches the 32-bit value set in
the watchdog value registers. This value consists of two consecutive
16-bit register locations. The error flag sends a high signal to one of
the multipurpose pins. The watchdog function must be enabled
by setting the single-bit register at Location 57872 high.
The register configuration for the watchdog counter is as follows:
Watchdog enable is a 1-bit enable.
Watchdog Value 1 is the 16 MSBs of the watchdog
maximum count value.
Watchdog Value 2 is the 16 LSBs of the watchdog
maximum count value.

This single-bit watchdog error flag goes high when an error occurs.
It can optionally be sent to an MP pin, as described in the
Address 0xE20F) section. For example, the error flag can
connect to an interrupt pin on a microcontroller in the system.
It resets to 0 when the watchdog enable is reset to 0.
