RSVD1: These bits are reserved for future use.

RW_L
OVTATTACK: Override of Unsolicited Connection State Attack and Terminate.
0: Disable Override. Attack Terminate allowed.
1: Enable Override. Attack Terminate disallowed.
This register bit is locked when PAVPE is set.
3
0h
RW_L
HVYMODSEL: This bit is applicable only for PAVP2 operation mode. This bit is also
applicable for PAVP3 mode only if the per-App memory config is disabled due to the
clearing of bit 9 in the Crypto Function Control_1 register (address 0x320F0).
0: Lite Mode (Non-Serpent mode)
1: Serpent Mode
For enabled PAVP3 mode, this one type boot time programming has been replaced by
per-App programming (through the Media Crypto Copy command). Note that PAVP2 or
PAVP3 mode selection is done by programming bit 8 of the MFX_MODE - Video Mode
register.

0h
RW_KL
PAVPLCK: This bit locks all writeable contents in this register when set (including
itself). Only a hardware reset can unlock the register again. This lock bit needs to be
set only if PAVP is enabled (bit 1 of this register is asserted).

0h
RW_L
PAVPE:
0: PAVP functionality is disabled.
1: PAVP functionality is enabled.
This register is locked when PAVPLCK is set.
0
0h
RW_L
PCME: This field enables Protected Content Memory within Graphics Stolen Memory.
This memory is the same as the WOPCM area, whose size is defined by bit 5 of this
register. This register is locked when PAVPLOCK is set.
A value of 0 in this field indicates that Protected Content Memory is disabled, and
cannot be programmed in this manner when PAVP is enabled.
A value of 1 in this field indicates that Protected Content Memory is enabled, and is the
only programming option available when PAVP is enabled. (Note that the processor
legacy Lite mode programming of PCME bit = 0 is not supported. For non-PAVP3 Mode,
even for Lite mode configuration, this bit should be programmed to 1 and
HVYMODESEL = 0).
This bit should always be programmed to 1 if bits 1 and 2 (PAVPE and PAVP lock bits)
are both set. With per-App Memory configuration support, the range check for the
WOPCM memory area should always happen when this bit is set, regardless of Lite or
Serpent mode, or PAVP2 or PAVP3 mode programming.
