ISL5217_05 INTERSIL [Intersil Corporation], ISL5217_05 Datasheet - Page 32

• Manufacturer Part Number: ISL5217_05
• Description: Quad Programmable Up Converter
• Manufacturer: INTERSIL [Intersil Corporation]

NOTES:
25. The mask register enables the slave registers to be updated from a hardware or software strobe.
26. The mask register is not used when µP is updating a configuration slave register immediately.
27. There is no immediate update on the I strobe.
28. Update mask <1> only affects the top routing control nibble for this channel.

Not used
Soft reset. Self clearing pulse zeroes FIFO’s, zeroes data RAMs, and clears all but the master registers.
The device will reload the slave configuration registers on the next TX enable or update strobe
Software update Self clearing pulse allows µP write to load all configuration slave registers synchronously
as determined by the update mask. The software equivalent of the hardware Update strobe
