Note: When using the MCU Oscillator as a clock for an external device, an HC buffer should be
connected as indicated in the figure.

On-chip RC Oscillator
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.

AT90S1200
The AT90S1200 AVR RISC Microcontroller supports powerful and efficient addressing
modes. This section describes the different addressing modes supported in the
AT90S1200. In the figures, OP means the operation code part of the instruction word.
To simplify, not all figures show the exact location of the addressing bits.
