May
Genius 9880 points

Part Number: MSP430FR2476

Hi Team,

Good day, customer want to confirm regarding MSP430FR2476. 

Main Questions to page 76; missing SYSCFG3 register:
1e. Is SYSCFG3 available or not?
The "SYSCFG3" register can NOT be found in this documentation.
2e. When available: is the offset address = 26h?

Questions to page 17; remapping of USB0xxx and USB1xxx register:
1a. Are both USB0xxx and USB1xxx dependent on the setting of the bit in the remap register SYSCFG2.USCIBRM ?

Questions to page 17; missing and misspelled SYSCFG3 register:
1b. Should "SYCFG3" be spelled as "SYSCFG3"?
2b. Is SYSCFG3 available or not?
The "SYSCFG3" register can NOT be found in this documentation:
on page 76 in "Table 6-35. SYS Registers (Base Address: 0140h)" only SYSCFG2 is mentioned!

Question to page 18; missing footnote
1c. Is meant the same as the footnote on page 17?

Question to remapping on page 19
1d. Are both TA2 and TA3 dependent on the remap-bit SYSCFG3.TARMP ?

Question to page 70; setting of PxSEL.X for P5.3 and P5.4:
1f. Should this be "10" for TA3 ?

Thank you and looking forward for your kind response.

Regards,

Maynard

    SYSCFG3 is present in the FR2476. It is at address 0x166, which is offset 0x26 from SYSCTL[base] at 0x140.

    The definitions of SYSCFG2 and SYSCFG3 should be taken from User Guide (SLAU445I) Tables 1-31 and 1-32 (rather than 1-26  and 1-27). Until  the data sheet is updated, these will have to be authoritative.

    There are separate remap bits for USCIB0RMP and USCIB1RMP. The header file shows separate bits for TA2RMP and TA3RMP (I haven't had occasion to use the TAxRMP bits myself but I expect they're there.) As far as I know the ADCPCTLn bits are not present on the FR2476.

    I suspect you're correct about the P5SEL settings in data sheet (SLASEO7B) Table 6-27, but I haven't had occasion to use those functions.

    There's a "Submit Documentation Feedback" link at the bottom of each doc page. I reported the RMP things a few months ago, but I haven't seen an update yet.

    Hi 

    Bruce is correct. SYSCFG3 is missed at page 76. The offset is 0x26.

    Same with USCIB0 and USCIB1

    I think you are correct.
