H3
ANC_BLANK
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to enable or disable ANC data blanking.
When set LOW, the HANC and VANC data is mapped to the appropriate
blanking levels.
H4
LOCKED
Synchronous
with PCLK
Output
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS / LVTTL compatible.
This signal is set HIGH by the device when the internal PLL has
achieved lock to the supplied PCLK signal.
This pin is set LOW by the device under all other conditions.
IO_VDD = 3.3V
Drive Strength = 8mA
IO_VDD = 1.8V
Drive Strength = 4mA
H5
GRP2_EN/DIS
Non
Synchronous
Input
Enable Input for Audio Group 2.
H6
GRP1_EN/DIS
Non
Synchronous
Input
Enable Input for Audio Group 1.
H7
AUDIO_INT
Non
Synchronous
Output
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Summary Interrupt from Audio Processing.
This signal is set HIGH by the device to indicate a problem with the
audio processing which requires the Host processor to interrogate the
interrupt status registers.
IO_VDD = 3.3V
Drive Strength = 8mA
IO_VDD = 1.8V
Drive Strength = 4mA
H8
JTAG/HOST
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select JTAG Test Mode or Host Interface Mode.
When set HIGH, CS_TMS, SDOUT_TDO, SDI_TDI and SCLK_TCK are
configured for JTAG boundary scan testing.
When set LOW, CS_TMS, SDOUT_TDO, SDI_TDI and SCLK_TCK are
configured as Gennum Serial Peripheral Interface (GSPI) pins for
normal host interface operation.
