Notes
1.
Pin type abbreviations: I = Input, O = Output, I/O = Input or Output, O/Z = high impedance Output and
S = Supply voltage.
5 V tolerant outputs swing between V
SS
and V
DD
. 5 V tolerant inputs can receive signals swinging between V
SS
and
3.3 V or V
SS
and 5 V.
SignalCPU_SEL(1) isused only afteraglobal hardware reset isapplied onexternal input lineRESET fordetermining
the type of the microcontroller connected to SAA7215; SAA7216; SAA7221 and therefore apply the proper
communication protocol. This microcontroller type must be given by means of weak pull-up or pull-down externally
connected to CPU_SEL(1). During normal operation, the pin TTXRQ/CPU_SEL(1) is used for implementing the
Teletext Data Request protocol and must not be disturbed by the microcontroller type setting.
