Reset:
• TCLR: CLE to REN Low Delay
Command Latch Enable falling edge to Read Enable falling edge timing.
Latch Enable Falling to Read Enable Falling = (TCLR[3] * 64) + TCLR[2:0] clock cycles.
• TADL: ALE to Data Start
Last address latch cycle to the first rising edge of WEN for data input.
Last address latch to first rising edge of WEN = (TADL[3] * 64) + TADL[2:0] clock cycles.
• TAR: ALE to REN Low Delay
Address Latch Enable falling edge to Read Enable falling edge timing.
Address Latch Enable to Read Enable = (TAR[3] * 64) + TAR[2:0] clock cycles.
• OCMS: Off Chip Memory Scrambling Enable
When set to one, the memory scrambling is activated.
• TRR: Ready to REN Low Delay
Ready/Busy signal to Read Enable falling edge timing.
Read to REN = (TRR[3] * 64) + TRR[2:0] clock cycles.
• TWB: WEN High to REN to Busy
Write Enable rising edge to Ready/Busy falling edge timing.
Write Enable to Read/Busy = (TWB[3] * 64) + TWB[2:0] clock cycles.
• RBNSEL: Ready/Busy Line Selection
This field indicates the selected Ready/Busy Line from the RBN bundle.
• NFSEL: NAND Flash Selection
If this bit is set to one, the chip select is assigned to NAND Flash write enable and read enable lines drive the Error Correct-
ing Code module.
