Machine address. RAM address pointer for the command executed. This field is incremented by 1, each time
the UPM is accessed and the OP field is set to WRITE or READ. Address range is 64 words per UPM n .
Refresh timers prescaler. Determines the period of the refresh timers input clock. The system clock is divided
by PTP except when the value is 00000_0000, which represents the maximum divider of 256.
