11 8 SYSCL K /XI I
System Clock input pin / Oscillator pin
The clock used as a system clock besides
I2C, SPI, and CEC is inputted.
This can use a crystal oscillator by
combining it with NC/XO pin.
In any case, please input 27 M
H z.
11 9 NC/XO O
Open pin / Oscillator pin
This can use a crystal oscillator by
combining it with SYSCL
K /XI pin.

11 4 H SCL0 I
H OST IF 0 host clock
* When this is pulled up externally, the
recommended value is 4 .7k to 10k Ohm.
11 6 H SDA0 I/O
H OST IF 0 host data
* Because this is an open drain pin, it
should be pulled up externally.
The recommended value is
4 .7k to 10k Ohm.
68 NIRQ1 O
Interrupting flag for H DMI control Low
Active
* Because this is an open drain pin, it
should be pulled up externally.
The recommended value is
4 .7k to 10k Ohm.
13 NIRQA0 O
Interrupting flag for Audio Output 0 control
Low Active
* Because this is an open drain pin, it
should be pulled up externally.
The recommended value is
4 .7k to 10k Ohm.
12 NOSDIRQ O
Interrupting flag for OSD control Low Active
* Because this is an open drain pin, it
should be pulled up externally.
The recommended value is
4 .7k to 10k Ohm.
