123 / 165 page  R01DS0060EJ0100 Rev.1.00 Page 123 of 168 Sep 13, 2011 RX630 Group 5. Electrical Characteristics 5.4 Clock Timing Note 1. This is the time until the clock is used after setting P36 and P37 as inputs, and then clearing the main clock-oscillator stop bit (MOSCCR.MOSTP) to 0 (selecting operation). Note 2. This is the time until the frequency of oscillation by the HOCO (fHOCO) reaches the range for guaranteed operation. after release from the reset state. Table 5.9 Clock Timing (Except for Sub-Clock Related) Conditions: VCC = AVCC0 = VCC_USB = VBATT = 2.7 to 3.6 V, VREFH/VREFH0 = 2.7 V to AVCC0, VSS = AVSS0 = VREFL/VREFL0 = VSS_USB = 0 V, Ta = Topr Item Symbol Min.
