Figure 2. Oscillator Connections
Note:
Figure 3. External Clock Drive Configuration
An On-chip RC Oscillator running at a fixed frequency of 1 MHz can be selected as the
MCU clock source. If enabled, the AT90S1200 can operate with no external compo-
nents. A control bit (RCEN) in the Flash Memory selects the On-chip RC Oscillator as
the clock source when programmed (“0”). The AT90S1200 is normally shipped with this
bit unprogrammed (“1”). Parts with this bit programmed can be ordered as
AT90S1200A. The RCEN-bit can be changed by parallel programming only. When
using the On-chip RC Oscillator for Serial Program downloading, the RCEN bit must be
programmed in Parallel Programming mode first.
When using the MCU Oscillator as a clock for an external device, an HC buffer should be
connected as indicated in the figure.
