LED Mode Selection (MODE0~MODE3).
LED_MODE[1:0] can provide 4 LED display modes, Mode0~
Mode3.
LED_MODE1 is set by register16[15]. LED_MODE0 is
defined by pin or by register16[14]. The pin state of
LED_MODE0 is latched upon reset and set to register 16[14].
After power up, the designer can configure LED_MODE[1:0]
register during the operation.
Since LED_MODE1 is set to “0” upon reset, the designer can
set pin 55 to select “00” or “01” display mode if the register
16[15:14] is unchanged.
