3.10.22 HPRCTR: Hot Page Range Counter
This register contains the value of the Range counter which is used in the AutoRange mode. This
counter is initially loaded with the Hot Page Base (HPBASE) register. After each sample interval,
defined by the interval timer, the Range Counter is incremented to the next range of 512 address
blocks. When the Range Counter is incremented to an address higher than the HPMAX register
then the counter is pre-loaded with the value in the Hot Page Base register.

AutoRange Counter Address of the Counter Array
Corresponds to A[43:17]#.
Note: Least significant bits are ignored dependent on the resolution.
Therefore,
A[43:17]# valid when the resolution is 64 Bytes
A[43:23]# valid when the resolution is 4 KBytes
A[43:28]# valid when the resolution is 128 KBytes
A[43:34]# valid when the resolution is 8 MBytes
A[43:39]# valid when the resolution is 256 MBytes
