Preliminary data sheet
6.3 JTAG
6.4 NAND flash controller
The Joint Test Action Group (JTAG) interface allows the incorporation of the
LPC3130/3131 in a JTAG scan chain.
This module has the following features:
The NAND flash controller is used as a dedicated interface to NAND flash devices.
Figure 4
module is formed by a controller block that controls the flow of data from/to the AHB bus
through the NAND flash controller block to/from the (external) NAND flash. An error
correction encoder/decoder (ECC enc/dec) module allows for hardware error correction
for support of Multi-Level Cell (MLC) NAND flash devices.
Before data is written from the buffer to the NAND flash, optionally it is first protected by
an error correction code generated by the ECC module. After data is read from the NAND
flash, the error correction module corrects any errors.
This module has the following features:
