• Manufacturer Part Number: upd78f0730
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

Address: FFBAH
Note The TI000 pin valid edge is set by bits 5 and 4 (ES001, ES000) of prescaler mode register 00 (PRM00).
Symbol
TMC00
OVF00 is set to 1 when the value of TM00 changes from FFFFH to 0000H in all the operation modes (free-running
timer mode, clear & start mode entered by TI000 pin valid edge input, and clear & start mode entered upon a match
between TM00 and CR000).
It can also be set to 1 by writing 1 to OVF00.
