Hi,
I'm interfacing a nrf51822 and a H8/3294. My question is how much can I drain a the txd pin of the H8/3294. That means my question isn't really about nrf51822.
In documentation...
Hi,
On the 3.30 of nRF52832_Rev_1_Errata_v1.5.pdf, the sleep current with LFXO active is 0.5μA higher.

If you look at the circuit of the PCA10040, it uses a 32Mhz 12pF crystal.
C1 and C2 of the crystal are 12 pF.
However, you say to use this formula: C1 = C_L * 2 - 4pF...
I am testing the current consumption of SIM cards with PPK2.
When PPK2 is connected to VCC ( voltage 1.8 v or 3 v ), the PPK2 can display the current properly ( around 9...
