to read as “PAE is synchronized to the LOW-to-HIGH transition of RCLK
by one flip-flop and is LOW when the FIFO contains n or fewer unread
words.”
Updated “PAE is synchronized to the LOW-to-HIGH transition of WCLK by
one flip-flop and is set LOW when the number of unread words in the FIFO
is greater than or equal to CY7C4261 (16K-m) and CY7C4271 (32K-m).”
