2.4 FRAM Memory Wait States

The maximum FRAM memory access speed is 8 MHz. If the MCLK is operating faster than 8 MHz, wait-states are required to ensure reliable FRAM access. When using MCLK ≥ 8 MHz, configure the FRAM wait states in software before configuring the MCLK frequency.

  1. Configure the appropriate wait states.
    2. FRCTL0 = FRCTLPW | NWAITS_x
  2. Configure MCLK ≥ 8 MHz.

For more information, see the Wait State Control section of the FRAM Controller (FRCTRL) chapter in MSP430FR58xx, MSP430FR59xx, MSP430FR68xx, and MSP430FR69xx Family User's Guide.
