Functional
ACLK failure when crystal ESR is below 40 kOhm.
When ACLK is sourced by a low frequency crystal with an ESR below 40 kOhm, the duty cycle of ACLK may fall below the specification; the OFIFG may become set or in some instances, ACLK may stop completely.
Please refer to "XOSC8 Guidance" found at SLAA423 for information regarding working with this erratum.
