Table 4 Video output interface pins
1. The YC0 pin is tri-stated during reset and then sampled at the end of the reset to determine whether the EMI pins are
in STi5510 or STi5512 mode. If the YC0 pin is sampled high (i.e at VDD) then the STi5510 mode is selected for the EMI
pins and a low value selects STi5512 mode. For details see the External Memory interface chapter. In STi5512 mode the
address shift for bank 3 is dependent on the boot bank width and the strobe pins are tri-stated when the EMI bus is granted
to an external DMA device. External 10KΩ pull-up or pull-down resistors should be fitted to the YC0 according to the func-
tionality desired. If this pin is left not connected, the pin will be pulled high by an internal pull-up and will default the EMI
pins to STi5510 mode.
