Pin description
ST7LITEUS2, ST7LITEUS5
Legend/abbreviations for Table 2
Type: I = input, O = output, S = supply
In/Output level: CT= CMOS 0.3 VDD /0.7 VDD with input trigger
Output level: HS = High sink (on N-buffer only)
Port and control configuration
●
Input: float = floating, wpu = weak pull-up, int = interrupt, ana = analog
●
Output: OD = open drain, PP = push-pull
The RESET configuration of each pin is shown in bold which is valid as long as the device is
in reset state.

Caution: During normal operation
this pin must be pulled-up, internally
or externally (external pull-up of 10k
mandatory in noisy environment).
This is to avoid entering I2C mode
unexpectedly during a reset. In the
application, even if the pin is
configured as output, any reset will
put it back in pull-up

After a reset, the multiplexed PA3/RESET pin will act as RESET. To configure this pin as output (Port A3), write 55h to
MUXCR0 and AAh to MUXCR1. For further details, please refer to Section 6.5 on page 37.
