Table 1-1 Advisories Matrix

MODULE	DESCRIPTION	SILICON REVISIONS AFFECTED
MODULE	DESCRIPTION	E
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 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
SRAM	Advisory SRAM_01 — Reserved addresses within SRAM_MMR region alias into SRAM array	Yes
General-Purpose Timer	Advisory GPTM_01 — An incorrect value might be written to the general-purpose (GP) timers MMRs (memory mapped registers) when simultaneously accessing the PKA (public key accelerator) engine and/or the AES (advanced encryption standard) engine from a different master	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
ADC	Advisory ADC_04 — Misbehaving ADC FIFO status flags in the AUX_ANAIF:ADCFIFOSTAT register (OVERFLOW, FULL, ALMOST_FULL, and EMPTY)	Yes
ADC	Advisory ADC_05 — Writing any value to AUX_ANAIF:ADCTRIG.START will create an ADC trigger	Yes
