Return value
True if all parameters are valid and exclusive; otherwise false.
Category
Multi-function Timer Pulse Unit
Reference
R_MTU2_Set, R_MTU2_ControlChannel, R_MTU2_ControlUnit
Remarks
•
If an external clock input pin (MTCLKx) or I/O pin (MTIOCnx) is made active, this function will
configure that pin for input or output and disable other functions on that pin.
•
The alternative pins are assigned using function R_MTU2_Set.
•
Either R_MTU2_ControlChannel or R_MTU2_ControlUnit must be used to start the timers.
•
If a callback function is specified, this function will enable the relevant CPU interrupt.
Please see the notes on callback function usage in §6.
•
A callback function is executed by the interrupt processing function. This means that no other
interrupt can be processed until the callback function has completed.
•
If the channel is configured for phase counting mode, the counter clock source setting is ignored.
•
If buffer operation is selected for registers TGRA and TGRC, input capture / output compare is
not valid for register TGRC.
•
If buffer operation is selected for registers TGRB and TGRD, input capture / output compare is
not valid for register TGRD.
•
If synchronous mode is required, at least two channels must be enabled for synchronous
operation.
•
A companion function, R_MTU2_Create_load_defaults, can be used to load the default values
into the structure.
•
If the channel operation mode will be changed, ensure that the timer is stopped (use
R_MTU2_ControlChannel or R_MTU2_ControlUnit).
