12.0
Table 12-1 describes the commands used to generate addresses on the SRAM address bus. The index [15:0] field contains the
address of a 72-bit entry that results in a hit in 72-bit-configured quadrant. It is the address of the 72-bit entry that lies at the 144-bit
page, and the 288-bit page boundaries in 144-bit- and 288-bit-configured quadrants, respectively.
”Registers” on page 15 of this specification, describes the NFA and SSR registers. ADR[15:0] contains the address supplied on
the DQ bus during PIO access to the CYNSE70128. Command bits 8, 7, and 6 {CMD[8:6]} are passed from the command to the
SRAM address bus. See ”Commands” on page 21, for more information. ID[4:0] is the ID of the device driving the SRAM bus
(see ”Pinout Description” on page 130 for more information).
