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
Radio	Advisory Radio_05 — Zigbee has a negative 3dB RSSI offset error with internal bias	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, 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_06 — Device may fail to boot at temperatures below -5°C or under certain voltage conditions	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_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
