See section 9, Clock Generation Circuit in User's Manual for the relationship between the ICLK, PCLKA, PCLKB, PCLKC, PCLKD, FCLK, and BCLK frequencies. Note 3. The ADC12 cannot be used. 2.3.2 Clock Timing Table 2.12 Operation frequency value in Subosc-speed mode Item Symbol Min Typ Max Unit Operation frequency System clock (ICLK)*2 f 29.4 - 36.1 kHz Peripheral module clock (PCLKA)*2 - - 36.1 Peripheral module clock (PCLKB)*2 - - 36.1 Peripheral module clock (PCLKC)*2,*3 - - 36.1 Peripheral module clock (PCLKD)*2 - - 36.1 Flash interface clock (FCLK)*1, *2 29.4 - 36.1 External bus clock (BCLK)*2 - - 36.1 EBCLK pin output - - 36.1 Table 2.13 Clock timing except for sub-clock oscillator (1/2) Item Symbol Min Typ Max Unit Test conditions EBCLK pin output cycle time tBcyc 16.6 - - ns Figure 2.3 EBCLK pin output high pulse width tCH 3.3 - - ns EBCLK pin output low pulse width tCL 3.3 - - ns EBCLK pin output rise time tCr -- 5.0 ns EBCLK pin output fall time tCf -- 5.0 ns SDCLK pin output cycle time tSDcyc 8.33 - - ns SDCLK pin output high pulse width tCH 1.0 - - ns SDCLK pin output low pulse width tCL 1.0 - - ns SDCLK pin output rise time tCr -- 3.0 ns SDCLK pin output fall time tCf -- 3.0 ns EXTAL external clock input cycle time tEXcyc 41.66 - - ns Figure 2.4 EXTAL external clock input high pulse width tEXH 15.83 - - ns EXTAL external clock input low pulse width tEXL 15.83 - - ns EXTAL external clock rise time tEXr -- 5.0 ns EXTAL external clock fall time tEXf -- 5.0 ns Main clock oscillator frequency fMAIN 8- 24 MHz - Main clock oscillation stabilization wait time (crystal) *1 tMAINOSCWT -- -*1 ms Figure 2.5 LOCO clock oscillation frequency fLOCO 29.4912 32.768 36.0448 kHz - LOCO clock oscillation stabilization wait time tLOCOWT - - 60.4 μ s Figure 2.6 ILOCO clock oscillation frequency fILOCO 13.5 15 16.5 kHz - MOCO clock oscillation frequency FMOCO 7.2 8 8.8 MHz - MOCO clock oscillation stabilization wait time tMOCOWT - - 15.0 μ s- |
