current offset values. It is only possible to read offset values via parallel read.
rizes the control pins and sequence for both serial and parallel programming
modes. For a more detailed description, see discussion that follows.
TABLE 1 ⎯ STATUS FLAGS FOR IDT STANDARD MODE
NOTES:
1. n = Empty Offset, Default Values: n = 127 when parallel offset loading is selected or n = 1,023 when serial offset loading is selected.
2. m = Full Offset, Default Values: m = 127 when parallel offset loading is selected or m = 1,023 when serial offset loading is selected.
TABLE 2 ⎯ STATUS FLAGS FOR FWFT MODE
NOTES:
1. n = Empty Offset, Default Values: n = 127 when parallel offset loading is selected or n = 1,023 when serial offset loading is selected.
2. m = Full Offset, Default Values: m = 127 when parallel offset loading is selected or m = 1,023 when serial offset loading is selected.
