Notes
1. Pin type abbreviations: I = Input, O = Output, I/O = Input or Output, O/Z = high impedance Output and
2. 5 V tolerant outputs swing between V
3. Signal CPU_SEL(1) is used only after a global hardware reset is applied on external input line RESET for determining

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.
