TENn
(1) ~ (4)
(1) Setting SM pin to output mode by Port mode register assigned to SMn1 to SMn4 output
(2) Input clock is supplied to the macro by setting CAE = "1"
(3) Set compare register MCMPn0, MCMPn1
(4) Set TENn = "1" and ADBn0/1, DIRn0/1 bits by setting compare mode control register MCMPCn.
(5) Set PCE0/1 = "1", the counting operation/timing (with the specified counting selection) starts.
(6) Ensure that TENn = "0" (rewriting period longer than count period until overflow)
(7) Rewrite compare register MCMPn0, MCMPn1.
(8) Set TENn = "1" (ADBn1, ADBn0, DIRn1, DIRn0 can be written at the same time if necessary).
