1.6 Instruction Set
All instructions of the generic 8051 microcontroller are supported. A complete list of the instruction set
and of the associated op-codes is contained in the 73S12xxF Software User’s Guide.
1.7 Peripheral Descriptions
1.7.1 Oscillator and Clock Generation
The 73S1217F has two oscillator circuits; one for the main CPU clock and another for the RTC. The
main oscillator circuit is designed to operate with various crystal or external clock frequencies. An
internal divider working in conjunction with a PLL and VCO provides a 96MHz internal clock within the
73S1217F. 96 MHz is the required frequency for proper operation of specific peripheral blocks such as
the USB, specific timers, ISO 7816 UART and interfaces, Step-up converter, and keypad. The clock
generation and control circuits are shown in Figure 3.
