6.83 RTC3

RTC Module

Function

Unreliable write to RTC register

Description

A write access to the RTC registers (SEC, MIN, HOUR, DATE, MON, YEAR, DOW) may result in unexpected results. As a consequence the addressed register might not contain the written data, or some data can be accidentally written to other RTC registers.

Workaround

Use the RTC library routines, available as F541x/F543x code examples on the MSP430 Code Examples page (www.ti.com/msp430 > Software > Code Examples), which use carefully aligned MOV instructions. Library is listed as RTC_Workaround.zip and includes both CCE and IAR example projects that show proper usage. Using this library, full access to RTC registers is possible.
