Description
27
MODE[0]
I I/O switching input during external setting mode
28
MODE[1]
I (pulled-down by internal resistors)
29
MODE[2]
I Internal/external pins are switched by register MRA[0]
30
MODE[3]
I The default of register MRA[0] is external pin mode.
MODE [3:2] Output mode selection
00: ITU-RBT.656 (with 8-bit YCbCr SAV, EAV, blank processing)
01: 8-bit (YCbCr)
10: 16-bit (YCbCr) (ITU-RBT.601)
11: 24-bit RGB
MODE [1] Input mode selection
0: NTSC
1: PAL
Invalid if an ITU-RBT.601 signal is input while the register MRC[7] is set
to automatic NTSC/PAL recognition.

NTSC 4fsc can be set by register MRA [3:1] only.
I Not used. Be left open or fixed at "0" (pulled down by internal resistor).
I Not used. Be left open or fixed at "0" (pulled down by internal resistor).
I Not used. Be left open or fixed at "0" (pulled down by internal resistor).
I Not used. Be left open or fixed at "0" (pulled down by internal resistor).
I 0: normal operation, 1: sleep operation
I Reset input pin (active "L"). After powering ON, be sure to reset.
— Digital power supply
— Digital ground
I I2C-bus clock input
I/O I2C-bus data I/O pin
I Not used. Be left open or fixed at "0" (pulled down by internal resistor).
Clock select input pin (pulled down by internal resistor).
I 0: double-speed input mode 1: normal input mode
When a double-speed input mode is used, input a double frequency to system clock.
Data output B[7]: MSB, B[0]: LSB
During RGB output mode: B 8-bit data output
O
Other than RGB output mode: Hi-Z
Output mode is set by pin 27 or 28, or register MRA [7:6].
