I/O switching input during external setting mode
(pulled-down by internal resistors)
Internal/external pins are switched by register MRA[0]
The default of register MRA[0] is external pin mode.
MODE [3:2]
MODE [1] Input mode selection
Invalid if an ITU-RBT.601 signal is input while the register MRC[7] is set
to automatic NTSC/PAL recognition.
MODE [0] Input mode selection
NTSC 4fsc can be set by register MRA [3:1] only.
Not used. Be left open or fixed at "0" (pulled down by internal resistor).
Not used. Be left open or fixed at "0" (pulled down by internal resistor).
Not used. Be left open or fixed at "0" (pulled down by internal resistor).
Not used. Be left open or fixed at "0" (pulled down by internal resistor).
0: normal operation, 1: sleep operation
Reset input pin (active "L"). After powering ON, be sure to reset.

Not used. Be left open or fixed at "0" (pulled down by internal resistor).
Clock select input pin (pulled down by internal resistor).
0: double-speed input mode
When a double-speed input mode is used, input a double frequency to system clock.
Data output
During RGB output mode: B 8-bit data output
Other than RGB output mode: Hi-Z
Output mode is set by pin 27 or 28, or register MRA [7:6].
