• Manufacturer Part Number: upd70f3017ay
• Description: V850/sa1tm 32-/16-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

(3) 16-bit timer output control registers 0, 1 (TOC0, TOC1)
TOCn controls the operation of the timer n output controller by setting or resetting the R-S flip-flop (LV0), enabling
or disabling reverse output, enabling or disabling output of timer n, enabling or disabling one-shot pulse output
operation, and selecting the output trigger for the one-shot pulse by software.
TOCn is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears TOC0 and TOC1 to 00H.
Note The one-shot pulse output operates normally in the free-running mode and clear and start mode set
Cautions 1. Before setting TOCn, be sure to stop the timer operation.
(n = 0, 1)
After reset: 00H R/W
TOCn
by the valid edge of TIn0.
2. LVSn and LVRn are 0 when read after data has been set to them.
3. OSPTn is 0 when read because it is automatically cleared after data has been set.
4. Do not set OSPTn other than for one-shot pulse output.
