Manufacturer:PHILIPS Description:When reading data via the COUT pin and isolation resistor, the DQ line is left floating by the reading device. When RST is driven high, bit 17 is present on the COUT pin, which is fed back to the input DQ pin through the isolation resistor. When the CLK input transitions low to high, bit 17 is loaded into the first position of the I/O shift register and bit 16 becomes present on COUT and DQ of the next device. After 17 bits (or 17 times the number of DS1267s in the daisy chain), the data has shifted completely around and back to its original position. When RST transitions to the low state to end data transfer, the value (the same as before the read occurred) is loaded into the wiper-0, wiper-1, and stack select bit I/O register. |
