Reference

R_MTU_Destroy

Remarks • If an external clock input pin (TCLKx) or I/O pin (TIOCxn) is made active, this function will configure

that pin for input or output and disable other functions on that pin.

• The external clock inputs TCLKA, TCLKB, TCLKC and TCLKD are allocated to pins TCLKA-A,

TCLKB-A, TCLKC-A and TCLKD-A by default.

To select the –B group of pins, use API function R_PFC_Modify(5, 0x08, PDL_PFC_OR) to write 1 to bit

TCLKS in register PFCR5 before calling this function.

Note that these clock inputs are used by channels 0 to 5.

• 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.
