Fault interrupt enable. This read/write bit enables the generation of an interrupt when a fault is detected by
FTM and the FTM fault control is enabled.
0 Fault control interrupt is disabled.
1 Fault control interrupt is enabled.
FAULTIE bit is write protected, this bit can only be written if WPDIS = 1.
Fault control mode. These bits define the FTM fault control mode. The fault control mode is selected
according to the
The FAULTM[1:0] bits are write protected, these bits can only be written if WPDIS = 1.
Write protection disable. When write protection is enabled (WPDIS = 0), write protected bits can not be
written. When write protection is disabled (WPDIS = 1), write protected bits can be written. The WPDIS bit
is the negation of the WPEN bit. WPDIS is cleared when 1 is written to WPEN. WPDIS is set when WPEN
bit is read as a logic 1 and then 1 is written to WPDIS. Write 0 to WPDIS has no effect.
0 Write protection is enabled.
1 Write protection is disabled.
Initialize the output channels. When a logic 1 is written to INIT bit the output channels are initialized
according to the state of their corresponding bit in the FTMxOUTINIT register. Writing a logic 0 to INIT bit
has no effect.
0 The INIT bit is always read as logic 0.
FTM enable. When FTMEN = 1 all registers including the FTM specific registers (FTMxCNTINH through to
FTMxRFU) are available for use with no restrictions. When FTMEN = 0 only the TPM compatible registers
(FTMxSC through to FTMxC7VL) can be used without any restriction. The use of the FTM specific registers
when FTMEN = 0 is not recommended and can result in unpredictable behavior.
0 Only TPM compatible registers (FTMxSC through to FTMxC7VL) are available.
1 All FTM registers are available.
