20.2.6
Active Level Setting Register 1 (ALR1)
Note 1. Can be modified only once after a reset.
The ALR1 register specifies the active levels of the MTU outputs for detection of simultaneous conduction of those
outputs as reflected in the OCSR1 register.
OLSG0A Bit
(MTIOC3B Pin Active Level Setting)
This bit sets the active level of the MTIOC3B output. Specifically, setting the OLSG0A bit to 0 sets the low level and to
1 sets the high level as the active level for detection of simultaneous conduction.
OLSG0B Bit
(MTIOC3D Pin Active Level Setting)
This bit sets the active level of the MTIOC3D output. Specifically, setting the OLSG0B bit to 0 sets the low level and to
1 sets the high level as the active level for detection of simultaneous conduction.
OLSG1A Bit (MTIOC4A Pin Active Level Setting)
This bit sets the active level of the MTIOC4A output. Specifically, setting the OLSG1A bit to 0 sets the low level and to
1 sets the high level as the active level for detection of simultaneous conduction.
OLSG1B Bit (MTIOC4C Pin Active Level Setting)
This bit sets the active level of the MTIOC4C output. Specifically, setting the OLSG1B bit to 0 sets the low level and to
1 sets the high level as the active level for detection of simultaneous conduction.
