Address: FFB6H
Note The TI001 pin valid edge is set by bits 5 and 4 (ES011, ES010) of prescaler mode register 01 (PRM01).
Symbol
TMC01
OVF01 is set to 1 when the value of TM01 changes from FFFFH to 0000H in all the operation modes (free-running
timer mode, clear & start mode entered by TI001 pin valid edge input, and clear & start mode entered upon a match
between TM01 and CR001).
It can also be set to 1 by writing 1 to OVF01.
