Rev. 1.4
All ports on the chip are bi-directional. Each consists of a Latch (SFR ‘USR70’), an output driver, and an
input buffer, therefore the MPU can output or read data through any of these ports if they are not used for
alternate purposes.
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.

Oscillator and Clock Generation
The 73S1210F has one oscillator circuit for the main CPU clock. 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 73S1210F. 96 MHz is the recommended
frequency for proper operation of specific peripheral blocks such as the specific timers, ISO 7816 UART
and interfaces, Step-up converter, and keypad. The clock generation and control circuits are shown in
