V
ZT
: Value at which the digital conversion value changes from
00h to 01h and vice versa.
2
V
FT
: Value at which the digital conversion value changes from
FEh to FFh and vice versa.

f
ADC
indicates the below values due to the contents of bit 6 (CKS)
of the A/D control register (ADC: 00F9h) and bits 7 (PCK1) and 6
(PCK0) of the clock control register (CLC: 00FEh).
f
ADC
= fc (CKS = "0"), fc/2 (CKS = "1")
However, the selection for f
ADC
= fc (CKS = "0") is
limited in the clock range of fc = 1 to 14MHz (V
DD
= 4.5
to 5.5V).
