PARAMETER MEASUREMENT INFORMATION (CONTINUED)
timing parameter symbology
Timing parameter symbols used in this document are in accordance with JEDEC Standard 100-A. Unless
otherwise noted, in order to shorten the symbols, pin names and other related terminology have been
abbreviated as follows:
A
A23– A0 when the physical-memory-width-bit field of the STRBx control register is set to 32 bits
A23 – A0 and STRBx_B3/A–1 when the physical-memory-width-bit field of the STRBx control register is
set to 16 bits
A23 – A0, STRBx_B3/A–1, and STRBx_B2/A–2 when the physical-memory-width-bit field of the STRBx
control register is set to 8 bits
CI
CLKIN
RDY RDY
D
D(31 – 0)
H
H1, H3
IOS
IOSTRB
Ptc(H)
Qtc(CI)
RW
R / W
S
STRBx_B(3– 0) when the physical-memory-width-bit field of the STRBx control register is set to 32 bits
STRBx_B(1– 0) when the physical-memory-width-bit field of the STRBx control register is set to 16 bits
STRBx_B0 when the physical-memory-width-bit field of the STRBx control register is set to 8 bits
