18.4.3
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when the A/D conversion start delay time (t
1, then starts A/D conversion. Figure 18.2 shows the A/D conversion timing. Table 18.3 indicates
the A/D conversion time.
As indicated in figure 18.2, the A/D conversion time (t
(t
conversion time therefore varies within the ranges indicated in table 18.3.
In scan mode, the values given in table 18.3 apply to the first conversion time. In the second and
subsequent conversions, the conversion time is 266 states (fixed) when CKS = 0 and 134 states
(fixed) when CKS = 1.
Use the conversion time of 134 state only when the system clock (φ) is 16 MHz or lower.
