GDU_PHCMP2CR1 field descriptionsField Description7SESample EnableAt any given time, either SE or WE can be set. If a write to this register attempts to set both, then SE is setand WE is cleared. However, avoid writing ones to both bit locations because this "11" case is reservedand may change in future implementations.0 Sampling mode not selected.1 Sampling mode selected.6WEWindowing EnableAt any given time, either SE or WE can be set. If a write to this register attempts to set both, then SE is setand WE is cleared. However, avoid writing ones to both bit locations because this "11" case is reservedand may change in future implementations.0 Windowing mode not selected.1 Windowing mode selected.5ReservedThis field is reserved.This read-only field is reserved and always has the value 0.4PMODEPower Mode Select0 Low Speed (LS) comparison mode selected.1 High Speed (HS) comparison mode selected.3INVGDU Comparator INVERTThis bit allows you to select the polarity of the GDU analog comparator function. It is also driven to theCOUT output (on both the device pin and as SCR[COUT]) when CR1[OPE]=0.0 Does not invert the GDU comparator output.1 Inverts the GDU comparator output.2COSComparator Output SelectNOTE: This field is always disabled in this device, writing 1 to this field does not take effect.0 Set CMPO to equal COUT (filtered comparator output).1 Set CMPO to equal COUTA (unfiltered comparator output).1OPEComparator Output Pin EnableNOTE: This field is always disabled in this device, writing 1 to this field does not take effect.0 The comparator output (CMPO) is not available on the associated CMPO output pin.1 The comparator output (CMPO) is available on the associated CMPO output pin.0ENComparator Module EnableThe EN bit enables the Analog Comparator Module. When the module is not enabled, it remains in the offstate, and consumes no power. When you select the same input from analog mux to the positive andnegative port, the comparator is disabled automatically.0 Analog Comparator disabled.1 Analog Comparator enabled.Chapter 25 Gate Drive Unit (GDU)MC9S08SU16 Reference Manual, Rev. 5, 4/2017NXP Semiconductors 447
