36 / 468 page  36 8152G–AVR–11/09 ATmega164PA/324PA/644PA/1284P Ce - is optional external capacitors as described in Figure 8-2 on page 32 Ci - is is the pin capacitance in Table 8-8 on page 35 CL - is the load capacitance for a 32.768 kHz crystal specified by the crystal vendor. C S - is the total stray capacitance for one TOSC pin. Crystals specifying load capacitance (CL) higher than the ones given in the Table 8-8 on page 35, require external capacitors applied as described in Figure 8-2 on page 32. Figure 8-3. Crystal Oscillator Connections Crystals specifying load capacitance (CL) higher than listed in Table 8-8 on page 35, require external capacitors applied as described in Figure 8-2 on page 32. To find suitable load capacitance for a 32.768 kHz crysal, please consult the crystal datasheet. When this oscillator is selected, start-up times are determined by the SUT Fuses and CKSEL0 as shown in Table 8-9. Note: 1. These options should only be used if frequency stability at start-up is not important for the application. Table 8-9. Start-up Times for the Low Frequency Crystal Oscillator Clock Selection Power Conditions Start-up Time from Power-down and Power-save Additional Delay from Reset (VCC = 5.0V) CKSEL0 SUT1..0 BOD enabled 1K CK 14CK(1) 000 Fast rising power 1K CK 14CK + 4.1 ms(1) 001 Slowly rising power 1K CK 14CK + 65 ms(1) 010 Reserved 0 11 BOD enabled 32K CK 14CK 1 00 Fast rising power 32K CK 14CK + 4.1 ms 1 01 Slowly rising power 32K CK 14CK + 65 ms 1 10 Reserved 1 11 |
