LPC43xx User manual
•
Table 777 “SCT configuration example” updated and moved to Chapter 31.
•
Number of EMC_CS and EMC_DYCS pins corrected for the LQFP208 pin package in Table 409
“EMC pinout for different packages”.
•
Section 40.7.5.1 “USART clock in synchronous mode” added.
•
Bit 12 changed to 1 for EMC address mapping 256 Mb, 512 Mb, 1 Gb. See Table 433 “Address
mapping”.
•
Bit description of bits TSEG1 and TSEG2 corrected in Table 1037 “CAN bit timing register (BT,
address 0x400E 200C (C_CAN0) and 0x400A 400C (C_CAN1)) bit description” and Figure 170 “Bit
timing” updated for clarity.
•
Parts MX1635E, W25Q16DV, W25Q32FV added to Table 25 “QSPI devices supported by the boot
code and the SPIFI API”.
•
Use of IAP calls clarified: IAP commands are not supported for flash-less parts. See Section 6.8 “IAP
commands”.
•
For flashless parts only: Unique part ID is stored in OTP bank 0 and readable at memory locations
0x4004 5000.to 0x4004 500C. See Section 4.1 and Table 14 “OTP memory description (OTP base
address 0x4004 5000)”.
•
For secure parts only: Chapter 7 “LPC43Sxx Boot ROM for secure parts” added.
•
For secure parts only: AES DMA request lines added. See Table 100, Table 330, and Table 350.
•
Boot ROM chapter split into two chapters for secure and non-secure parts. See Chapter 5 “LPC43xx
Boot ROM” and Chapter 7 “LPC43Sxx Boot ROM for secure parts”.
•
Section 5.1.1 “Determine the boot code version” added.
•
Signal polarity of signals EMC_CKEOUT and EMC_DQMOUT corrected in Table 412 “EMC pin
description”. Both signals are active HIGH.
•
IRC accuracy corrected in Section 1.2 “Features”.
•
Added text: The secure boot from USART3 is not supported for LPC43Sxx parts: see Section 5.1,
Section 7.1, Table 21, and Table 22.
