MCU Microprocessor power supply
HDMI power supply ON/OFF control / H: ON, L: OFF
O
When V2065 uses CEC microprocessor, HDMI EQ (CXB1442, SiI9185A) reset
may be used
Video power supply ON/OFF control / H: ON, L: OFF
O
Configured based on the Pure Direct specification
SubCPU reset
Because the delay circuit of 2 ms is passed so that it may
O
discriminate against reset of Flash and BlackFin, it is
necessary to secure the change time of 5 ms or more.
