Active Profile

When the DPLL selects a specific translation profile, whether

manually or automatically, the selected profile becomes active.

When a translation profile is active, the corresponding bit is

Logic 1 in Register 0x3009 (DPLL0) or Register 0x300A

(DPLL1). Bits[5:0] associate with Translation Profile x.5

through Translation Profile x.0, respectively, where x = 0 or 1.

The IRQ status section of the register map indicates Logic 0 to

Logic 1 transitions of Bits[5:0] of Register 0x3013 (DPLL0) and

the user must clear them via Bits[5:0] of Register 0x200E (DPLL0)

and Register 0x2013 (DPLL1) to obtain visibility of subsequent

Logic 0 to Logic 1 transitions of Bits[5:0] in Register 0x3009

(DPLL0) and Register 0x300A (DPLL1) (see the Interrupt

Request (IRQ) section).

An active translation profile is not the same as a valid translation

profile. That is, a profile can be valid without being active.

When all translation profiles for a particular DPLL are inactive, the

user can find the most recently active profile via Bits[6:4] of

value of Bits[6:4] corresponds to the most recently active

profile. If a translation profile is currently active (as indicated

by Bits[5:0] in Register 0x3009 and Register 0x300A), the value

of Bits[6:4] in Register 0x3101 (DPLL0) and Register 0x3201

(DPLL1) identify the currently active profile.
