Notes 1: Counting is stopped by clearing to “0.”
2: When the T1AB instruction is executed after V1 0 is set to “1,”
writing is performed only to reload register R1.
3: The data of reload register R2L set with the T2AB instruction
can be also written to timer 2 with the T2R2L instruction.
4: The initializing signal is output at reset or RAM back-up mode.
