Table 1-1 Advisories Matrix

MODULE	DESCRIPTION	SILICON REVISIONS AFFECTED
MODULE	DESCRIPTION	B
Radio	Advisory Radio_01 — Proprietary radio modes: spurious emissions can affect regulatory compliance	Yes
Power	Advisory Power_03 — Increased voltage ripple at low supply voltages when DC/DC converter is enabled	Yes
PKA	Advisory PKA_01 — Public key accelerator (PKA) interrupt line is always high when module is enabled and PKA is idle	Yes
PKA	Advisory PKA_02 — Public key accelerator (PKA) RAM is not byte accessible	Yes
I2C	Advisory I2C_01 — I²C module master status bit is set late	Yes
I2S	Advisory I2S_01 — I²S bus faults are not reported	Yes
CPU	Advisory CPU_01 — Arm® Errata #838869: Store immediate overlapping exception return operation might vector to incorrect interrupt	Yes
CPU	Advisory CPU_02 — Arm® Errata #752770: Interrupted loads to SP can cause erroneous behavior	Yes
CPU	Advisory CPU_03 — Arm® Errata #776924 VDIV or VSQRT instructions might not complete correctly when very short ISRs are used	Yes
CPU, System	Advisory CPU_Sys_01 — The SysTick calibration value (register field CPU_SCS.STCR.TENMS) used to set up 10-ms periodic ticks is incorrect when the system CPU is running off divided down 48-MHz clock	Yes
System	Advisory Sys_01 — Device might boot into ROM serial bootloader when waking up from shutdown	Yes
System	Advisory Sys_05 — Elevated power-on-reset (POR) threshold voltage at low temperatures	Yes
System Controller	Advisory SYSCTRL_01 — Resets occurring in a specific 2-MHz period during initial power up are incorrectly reported	Yes
IO Controller	Advisory IOC_01 — Limited number of DIOs available for the bootloader backdoor	Yes
ADC	Advisory ADC_01 — Periodic ADC trigger at 200 kHz rate can be ignored when XOSC_HF is turned on or off	Yes
ADC	Advisory ADC_02 — ADC samples can be delayed by 2 or 14 clock cycles (24 MHz) when XOSC_HF is turned on or off, resulting in sample jitter	Yes
ADC	Advisory ADC_03 — Software can hang when reading the ADC FIFO if a single manual ADC trigger is generated immediately after the ADC is enabled	Yes
