Writing to the Registers

Status/Control Register

Channel Enable Registers

You can write to the following RF multiplexer registers:

∙Status/Control register (base + 04h)

∙Bank 0 Channel Enable register (base + 08h)

∙Bank 1 Channel Enable register (base + Ah)

The only write allowed to the Status/Control register (base + 04h) is to bit 0. Writing a “ 1” to bit 0 resets the multiplexer to its power-on state with all channels open and terminated and both commons open.

Writes to the Channel Enable registers (base + 08h and base + Ah) enabling you to open or close the desired channel (see Register Defintions at the beginning of this chapter). For example, write a “ 1” to bit 2 of the bank 0 Channel Enable register to close channel 02. Or, write a “ 1” to bit 3 of the Bank 1 Channel Enable register to close channel 13. Writing a “ 0” to bits 0 - 3 results in all channels open and terminated and the common open. Only one channel per bank can be closed at a time. Any bit pattern not shown in Register Defintions at the beginning of this chapter, results in the lowest-numbered channel being closed.
