Pin Function (2/5)
1. The digital encoder video outputs are analogue signals and are not 5V tolerant. The same applies to the video DAC
voltage and current reference pins.
2. 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. 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 functionality desired. If this pin is left
be pulled high by an internal pull-up and will default the EMI pins to STi5510 mode.

1. This pin is tri-stated during reset and then sampled at the end of the reset to determine whether the OS-Link is active and
to determine the function of the shared CPUAnalyse / TrigIn and the ErrorOut / TrigOut, as described in the System Serv-
ices chapter. If the ErrorOut pin is sampled high (i.e at VDD) then the DCU signals (TrigIn and TrigOut) are selected and a
low value indicates OS-Link signals (i.e. CPUAnalyse, ErrorOut) are to be used. External 10KΩ pull-up or pull-down resis-
tors should be fitted to the ErrorOut according to the functionality desired.
