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 initializing signal is output at reset or RAM back-up mode.
: Data is automatically set from a reload register
when timer 1 underflows (auto-reload function).
