5.6.6 CPU clock status transition diagram
Figure 5-18. CPU Clock Status Transition Diagram (When LVI Default Start Mode Function Stopped Is Set
Figure 5-18 and 5-19 shows the CPU clock status transition diagram of this product.
Remark When LVI default start function enabled is set (option byte: LVISTART = 1), the CPU clock status
changes to (A) in the above figure when the supply voltage exceeds 1.91 V (TYP.), and to (B) after reset
processing.
(Option Byte: LVISTART = 0), 78K0/KY2-L, 78K0/KA2-L, and 78K0/KB2-L)
