... When software writes any port pin, the DS80C310 will activate a strong pulldown that remains on until either written or a reset occurs. Writing a 1 after the port has been at 0 will cause a strong transition driver to turn on, followed by a weaker sustaining pullup ...

... COMPATIBILITY The DS80C310 is a fully static CMOS 8051-compatible microcontroller designed for high performance. In most cases the DS80C310 can drop into an existing socket for the 80C31 or 80C32 to improve the operation significantly. In general, software written for existing 8051-based systems works without modification on the DS80C310. The exception is critical timing since the High-Speed Micro performs its instructions much faster than the original for any given crystal selection ...

... In the DS80C310, the MOVX instruction takes as little as two machine cycles or eight oscillator cycles but the “MOV direct, direct” uses three machine cycles or 12 oscillator cycles. While both are faster than their original counterparts, they now have different execution times. This is because the DS80C310 usually uses one instruction cycle for each instruction byte ...

... SPECIAL FUNCTION REGISTERS Special Function Registers (SFRs) control most special features of the DS80C310. The High-Speed Microcontroller User’s Guide describes all SFRs. Functions that are not part of the standard 80C32 are in bold. SPECIAL FUNCTION REGISTERS Table 2 REGISTER BIT 7 BIT 6 SP DPL ...

... STRETCH MEMORY CYCLE The DS80C310 allows the application software to adjust the speed of data memory access. The micro is capable of performing the MOVX in as few as two instruction cycles. However, this value can be stretched as needed so that both fast memory and slow memory or peripherals can be accessed with no glue logic ...

... CKCON bit is a logic 1, the DS80C310 uses 4 clocks per cycle to generate timer speeds. When the bit the DS80C310 uses 12 clocks for timer speeds. The reset condition CKCON.5 selects the speed of Timer 2. CKCON.4 selects Timer 1 and CKCON.3 selects Timer 0. Note that unless a user desires very fast timing unnecessary to alter these bits ...

... POWER ON RESET The DS80C310 will hold itself in reset during a power-up until 65,536 clock cycles have elapsed. The power-on reset used by the DS80C310 differs somewhat from other members of the High-Speed Microcontroller family. The crystal oscillator may start anywhere between 1.0V and 4.5V but is not specified ...
