Scrub Prescaler Counter (Bits 7-0)
This register reflects the current value in the scrub prescaler bits 7-0.
Scrub Timer Counter (Bits 15-8)
This read/write register is the Scrub Timer counter. If scrubbing is enabled
and the Scrub Period register is non-zero, the Scrub Timer counter
increments approximately once every two seconds until it matches the
value programmed into the Scrub Period register, at which time it clears
and resumes incrementing. Writes to this address update the Scrub Timer
counter and reads to this address yield the counter’s value. The ability to
read and write this register is provided for test purposes. Programming this
counter is not recommended. This register reflects the current value in the
Scrub Timer counter bits 15-8.
