72 / 108 page  R01DS0202EJ0120 Rev.1.20 Page 72 of 108 Jul 29, 2016 RX110 Group 5. Electrical Characteristics 5.3.5 Timing of On-Chip Peripheral Modules Note 1. tPcyc: PCLK cycle Note 2. tcac: CAC count clock source cycle Note 3. When the LOCO is selected as the clock output source (CKOCR.CKOSEL[2:0] bits = 000b), set the clock output division ratio selection to divided by 2 (CKOCR.CKODIV[2:0] bits = 001b). Note 4. When the XTAL external clock input or an oscillator is used with divided by 1 (CKOCR.CKOSEL[2:0] bits = 010b and CKOCR.CKODIV[2:0] bits = 000b) to output from CLKOUT, the above should be satisfied with an input duty cycle of 45 to 55%. Table 5.30 Timing of On-Chip Peripheral Modules (1) Conditions: 1.8 V ≤ VCC ≤ 3.6 V, 1.8 V ≤ AVCC0 ≤ 3.6 V, VSS = AVSS0 = 0 V, T a = –40 to +105°C Item Symbol Min. Max.
