Change log
New and inherited anomalies
[20] RTC: Register values are invalid
[36] CLOCK: Some registers are not reset when expected
[55] I2S: RXPTRUPD and TXPTRUPD events asserted after STOP
[66] TEMP: Linearity specification not met with default settings
[78] TIMER: High current consumption when using timer STOP task only
[81] GPIO: PIN_CNF is not retained when in debug interface mode
[87] CPU: Unexpected wake from System ON Idle when using FPU
[94] USBD: BUSSTATE register is not functional
[122] QSPI: QSPI uses current after being disabled
[136] System: Bits in RESETREAS are set when they should not be
[153] RADIO: RSSI parameter adjustment
[155] GPIOTE: IN event may occur more than once on input edge
[166] USBD: ISO double buffering not functional
[170] I2S: NRF_I2S->PSEL CONNECT fields are not readable
[171] USB,USBD: USB might not power up
[173] GPIO: Writes to LATCH register take several CPU cycles to take effect
[174] SPIM: SPIM3 events incorrectly connected to the PPI
[176] System: Flash erase through CTRL-AP fails due to watchdog time-out
[179] RTC: COMPARE event is generated twice from a single RTC compare match
[183] PWM: False SEQEND[0] and SEQEND[1] events
[184] NVMC: Erase or write operations from the external debugger fail when CPU is not halted
[186] POWER: High current consumption in System ON Idle, using High Voltage mode
[187] USBD: USB cannot be enabled
[189] SPIM: RX buffer error at 32 MHz operation
[190] NFCT: Event FIELDDETECTED may be generated too early
[191] RADIO: High packet error rate in BLE Long Range mode
[192] CLOCK: LFRC frequency offset after calibration
[193] SPIM: SPIM3 does not generate EVENTS_END and halts if suspended during last byte
[194] I2S: STOP task does not switch off all resources
[195] SPIM: SPIM3 continues to draw current after disable
[196] I2S: PSEL acquires GPIOs regardless of ENABLE
[198] nRF52840: SPIM3 transmit data might be corrupted
