of power, the MC145574 should be reset. This pin is a Schmitt–trigger input and could have an external
RC circuit connected to perform the power–on reset function.
The MC145574 S/T transceiver is always TTL/CMOS level compatible on all digital input pins.
The MC145574 is always CMOS level compatible on all digital output pins.
The MC145574 S/T transceiver has the capability of forcing all outputs (both analog and digital) to
the high–impedance state. This feature, known as the “serial control port high–impedance digital output
mode” is provided to allow “in–circuit” testing of other circuits or devices resident on the same PCB
without requiring the removal of the MC145574.
The SCP HIDOM mode is entered by holding SCPEN low for a minimum of 33 consecutive rising
edges of the SCPCLK while SCP Rx is high. If SCPEN goes high or if SCP Rx goes low, the device
exits the SCP HIDOM mode and returns to normal operation.
