Description
MTU2 PE0 High-Impedance Enable
This bit specifies whether to place the PE0/TIOC1A
pin for channel 0 in the MTU2 in high-impedance
state when either POE8F or MTU2CH0HIZ bit is set
to 1.
0: Does not place the pin in high-impedance state
1: Places the pin in high-impedance state
Description
Reserved
This bit is always read as 0. The write value should
always be 0.
MTU2 Port 1 Output Comparison/High-Impedance
Enable
This bit specifies whether to compare output levels for
the MTU2 high-current PE9/TIOC3B and
PE11/TIOC3D pins and to place them in high-
impedance state when the OSF1 bit is set to 1 while
the OEC1 bit is 1 or when any one of the POE0F,
POE1F, POE3F, and MTU2CH34HIZ bits is set to 1.
0: Does not compare output levels or place the pins in
1: Compares output levels and places the pins in
