MTU2SP2CZE 1
R/W* MTU2S Port 2 Output Comparison/High-Impedance
Enable
This bit specifies whether to compare output levels on
the MTU2 special pins, PE18/TIOC4AS and
PE20/TIOC4CS, and to place them in the high-
impedance state when the OSF2 bit is set to 1 while
the OCE2 bit is 1 or when any one of the POE4F,
POE5F, POE6F, POE7F, and MTU2SHIZ bits is set
to 1.
0: Does not compare output levels or place the pins in
the high-impedance state
1: Compares output levels and places the pins in the
high-impedance state
8
MTU2SP3CZE 1
R/W* MTU2S Port 3 Output Comparison/High-Impedance
Enable
This bit specifies whether to compare output levels on
the MTU2 special pins, PE19/TIOC4BS and
PE21/TIOC4DS, and to place them in the high-
impedance state when the OSF2 bit is set to 1 while
the OCE2 bit is 1 or when any one of the POE4F,
POE5F, POE6F, POE7F, and MTU2SHIZ bits is set
to 1.
0: Does not compare output levels or place the pins in
the high-impedance state
1: Compares output levels and places the pins in the
high-impedance state

These bits are always read as 0. The write value
should always be 0.
Note: * Can be modified only once after a power-on reset.
