97 / 179 page  R01DS0343EJ0120 Rev.1.20 Page 97 of 179 Nov 15, 2023 RX72N Group 2. Electrical Characteristics Note 1. If the main clock oscillator is selected by the CLKOUT output source select bit (CKOCR.CKOSEL[2:0]) and the external clock input is selected by the main clock oscillator switching bit (MOFCR.MOSEL), the pulse width depends on the input clock wave form. Figure 2.12 CLKOUT Pin Output Timing Figure 2.13 CLKOUT25M Pin Output Timing Table 2.21 CLKOUT Pin Output Timing Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = VBATT = 2.7 to 3.6 V, 2.7 V ≤ VREFH0 ≤ AVCC0, VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = 0 V, Ta = Topr, High-drive output is selected by the drive capacity control register Item Symbol Min.
