Type
Port 97: Programmable as input or open-drain output
Connection pin for a low-speed crystal
Ports A0–A3: Individually programmable as input or output
Interrupt Request 1–4: Individually programmable to be high-level, low-level, rising-
edge or falling-edge sensitive
Port A4: Programmable as input or output
Port A5: Programmable as input or output
Clock input/output pin when the Serial Bus Interface is in SIO mode
Port A6: Programmable as input or output
Data transmit pin when the Serial Bus Interface is in SIO mode
Data transmit/receive pin when the Serial Bus Interface is in I
as a push-pull or open-drain output
Port A7: Programmable as input or output
Data receive pin when the Serial Bus Interface is in SIO mode
Clock input/output pin when the Serial Bus Interface is in I
programmable as a push-pull or open-drain output
Address Latch Enable (This signal is driven out only when external memory is
accessed.)
Nonmaskable Interrupt Request: Causes an NMI interrupt on the falling edge
Both BW0 and BW1 should be tied to logic 1.
Test pin: This pin should be left open or tied to ground.
This pin should be tied to logic 1 when the frequency multiplied clock from the PLL is
used; otherwise, it should be tied to logic 0.
Reset (with internal pull-up resister): Initializes the whole TMP1940CYAF.
Input pin for high reference voltage for the A/D Converter. This pin should be
connected to the AVCC pin when the A/D Converter is not used.
Input pin for low reference voltage for the A/D Converter. This pin should be connected
to the AVSS pin when the A/D Converter is not used.
Power supply pin for the A/D Converter. This pin should always be connected to power
supply even when the A/D Converter is not used.
Ground pin for the A/D Converter. This pin should always be connected to ground
even when the A/D Converter is not used.
