The fast read instruction is terminated by driving nCS high at any time during data
output. Any fast read instruction is rejected during the Erase, Program, or Write
operations without any effect on the operation that is in progress.

Note to
(1) Address bit A[23] is a don't-care bit in EPCS64. Address bits A[23..21] are don't-care bits in EPCS16. Address
Read Silicon ID Operation
The read silicon ID operation code is b'1010 1011, with the MSB listed first. Only
EPCS1, EPCS4, EPCS16, and EPCS64 support this operation. It reads the serial
configuration device’s 8-bit silicon ID from the DATA output pin. If this operation is
shifted in during an erase or write cycle, it is ignored and has no effect on the cycle
that is in progress.

bits A[23..19] are don't-care bits in EPCS4. Address bits A[23..17] are don't-care bits in the EPCS1.
