In case that users select “delay time option A” and to use an internal oscillation circuit, and if setting “1” in B6 bit in the

D03 timer setting register, “1” in TS3 in the timer scale register, DO3 inverts at delay time of 35

µs (7 × 5 µs). Other

examples are shown in Figure 18.

Example 2-2

Example 1.

When using an internal CLK

Example 1-1 In case of; Timer scale register “1” (short-time setting), Delay time option “A” (

×1 setting); (T = 5 µs)

Example 1-2 In case of; Timer scale register “0” (long-time setting), Delay time option “A” (

×1 setting); (LT = 320 µs)

Example 2.

When using an external CLK (100 KHz, T’ = 10

µs)

Example 2-1 In case of; Timer scale register “1” (short-time setting), Delay time option “B” (

×2 setting); (T = 2 × T’ = 20 µs)

Example 2-2 In case of; Timer scale register “0” (long-time setting), Delay time option “B” (

×2 setting); (LT = 128 × T’ = 1280 µs)
