Table 1-1 Advisories Matrix

MODULE	DESCRIPTION	SILICON REVISIONS AFFECTED
MODULE	DESCRIPTION	C
Radio	Advisory Radio_01 — Proprietary radio modes: spurious emissions can affect regulatory compliance	Yes
Radio	Advisory Radio_02 — High-power PA operation at temperatures below -20°C may affect the 32 kHz crystal oscillator	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
CPU	Advisory CPU_04 — The Instrumentation Trace Macrocell (ITM) and Data Watchpoint and Trace (DWT) are active only if an external debug probe is attached to the JTAG port of the device	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
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
Flash	Advisory Flash_02 — Flash bank erase may timeout when operating at low temperatures with a low VDDS supply voltage	Yes
