Typical values are at T

1) The WK pin is configurable as input or as output which sent a trigger pulse on received trigger telegram. To configure this

change bit EN_OUT to “0” in Register TRIGGER (0x214). Default configuration is output.

2) The RESET pin is an open drain input/output with pull current source to V

IO

3) The input at pin RESET is not active in reset and startup modes and in case of low V

IO

4) In case of RESET activation by E981.03.
