DS1215 REGISTER ENTRY FLOWCHART Figure 17±3

Set ECE2 bit in the MCON

register to a logic 1

Perform a dummy read operation to reset clock pattern recognition circuit*

To open clock, write the 64±bit serial pattern by using A2 and A0 embedded address lines

*To guarantee that the pattern recognition circuit is reset to the first bit of the sequence it is highly rec- ommended that 65 read operations be performed. This is in case the DS5000T has been interrupted or reset while the clock was open.

Are clock time	Written
registers to be
read/written?
Read

Read time registers one bit at a time using read MOVX instructions that set A2 to logic 1. Bit to be read will be returned in bit 7 of data byte.

Write to time registers one bit at a time using write MOVX instructions that clear A2 to a logic 0. A0 should be the bit to be written.

Clear ECE2 to a zero to

access normal embedded
