Figure 1. Data Polling Algorithm
(Configuration Register = 00)
Notes:
1. VA = Valid address for programming. During a sec-
tor erase operation, a valid address is any sector
address within the sector being erased. During
chip erase, a valid address is any non-protected
sector address.
2. I/O7 should be rechecked even if I/O5 = “1”
because I/O7 may change simultaneously with
I/O5.
