Peripheral reset-control multiplexer
The EVB includes an 8-output multiplexer (U8) to reset the major peripherals (see
). Its outputs
are of a push–pull type (except for the unused open-drain Output 0).
When reset, all the outputs are in the high-impedance state; however, thanks to pull-down resistors on the
used outputs, the controlled peripherals are staying in the reset state until the outputs are actively driven
by the MCU over the I
2
C bus (address 0x30).
