[Description]
a. <ADCLK[2:0]>
Note 1: While AD conversion is executed with a clock selected in the register above, at this time, a conversion clock
Note 2: During AD conversion, do not switch the conversion clock.
AD Conversion Clock Setting Register
Selects the AD prescaler output.
AD conversion 1-clock period =
0y000: PCLK
0y001: PCLK/2
0y010: PCLK/4
0y011: PCLK/8
0y1xx: PCLK/16
ADCLK[2:0]
needs to be selected so that the AD conversion clock can be 33 MHz or less in order to meet the guaranteed
accuracy.
