EMIF1 Signal Descriptions (continued) SIGNAL NAME DESCRIPTION TYPE BOTTOM BALL TOP BALL ddr1_dqs1 Data strobe 1 input/output for byte 1 of the 32-bit data bus. This signal is output to the EMIF1 memory when writing and input when reading. IO J22 ddr1_dqs2 Data strobe 2 input/output for byte 2 of the 32-bit data bus. This signal is output to the EMIF1 memory when writing and input when reading. IO AB18 ddr1_dqs3 Data strobe 3 input/output for byte 3 of the 32-bit data bus. This signal is output to the EMIF1 memory when writing and input when reading. IO B18 ddr1_dqsn0 Data strobe 0 invert IO P22 ddr1_dqsn1 Data strobe 1 invert IO K23 ddr1_dqsn2 Data strobe 2 invert IO AC19 ddr1_dqsn3 Data strobe 3 invert IO A19 Feedthrough zq LPDDR2 Feedthrough to top ZQ pin FEED C7 P1 4.3.9 Timers NOTE For more information, see the Timers section of the device TRM.
