SDRAM read and write accesses are burst oriented starting at a selected location and continuing for a programmed number of locations in a programmed sequence. The registration of an ACTIVE command begins accesses, followed by a READ or WRITE command. The ACTIVE command in conjunction with address bits registered are used to select the bank and row to be accessed (BA0, BA1 select the bank; A0-A11 select the row). The READ or WRITE commands in conjunction with address bits reg- istered are used to select the starting column location for the burst access.
Port 1 C I/O. Port 1 functions as both an 8Cbit biCdirectional I/O port and an alternate functional interface for Timer 2 I/O, new External Interrupts, and new Serial Port 1. The reset condition of Port 1 is with all bits at a logic 1. In this state, a weak pullCup holds the port high. This condition also serves as an input mode, since any external circuit that writes to the port will overcome the weak pullCup. When software writes a 0 to any port pin, the Q10RTS8 will activate a strong pullCdown that remains on until either a 1 is 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 pullCup. Once the momentary strong driver turns off, the port again becomes the output high (and input) state. The alternate modes of Port 1 are outlined as follows.
Array Description The Q10RTS8 is comprised of a resistor array (see Figure 1). Each array contains 255 discrete resistive segments that are connected in series. The physical ends of each array are equivalent to the fixed terminals of a mechanical potentiometer (RH and RL inputs).
