External Clock
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in
Table
Table 8-13.
Note:
To drive the device from an external clock source, XTAL1 should be driven as shown in
8-4 on page
to “0000” (see
Table 8-14.
Figure 8-4.
When this clock source is selected, start-up times are determined by the SUT Fuses as shown in

1. If the RSTDISBL fuse is programmed, this start-up time will be increased to
14CK + 4.1 ms to ensure programming mode can be entered.
33. To run the device on an external clock, the CKSEL Fuses must be programmed
