(VCC
= 3.15 V to 3.6 V, VSS = AVSS = 0 V, TA = 0 °C to +70 °C)
*1 : Frequency regulation is the maximum fluctuation from a set center frequency, represented in percentage, when
locked to a multiple.
*2 : The target analog section is the A/D.
*3 : The maximum external bus operating frequency allowed is 25 MHz.
*4 : The value when a minimum clock frequency of 10 MHz is input to X0 and half a division of the oscillator circuit
and the 1/8 gear are in use.
