... WP ¯¯¯¯¯ : Hold HOLD ¯¯¯¯¯ pin is used to pause transmission to the CAT5261 while in the middle of a serial sequence without The HOLD having to retransmit entire sequence at a later time. To pause, HOLD SO pin high impedance state during the time the part is paused, and transitions on the SI pins will be ignored ...

... DEVICE OPERATION The CAT5261 is two resistor arrays integrated with an SPI serial interface logic, two 8-bit wiper control registers and eight 8-bit, non-volatile memory data registers. Each resistor array contains 255 separate resistive elements connected in series. The physical ends of each array are equivalent to the fixed ...

... The two least significant bits in the slave address byte A0, are the internal slave address and must match the physical device address which is defined by the state of the input pins for the CAT5261 to successfully continue the command sequence. Only the device which slave address matches the incoming device address sent by the master executes the instruction ...

... Finally loaded with the content of its data register zero (DR0) upon power-up. The Wiper Control Register is a volatile register that loses its contents when the CAT5261 is powered- down. Although the register is automatically loaded with the value in DR0 upon power-up, this may be different from the value present at power-down ...

... Four instructions require a two-byte sequence to complete, as illustrated in Figure 7. These instructions transfer data between the host/processor and the CAT5261; either between the host and one of the data registers or directly between the host and the Wiper Control Register. These instructions are: — XFR Data Register to Wiper Control Register This transfers the contents of one specified Data Register to the associated Wiper Control Register ...
