This anomaly applies to Revision 2, build code CAAA-Bxx.
It was inherited from the previous SoC revision Revision 1.
Symptoms
Static current consumption between 400 µA and 450 µA occurs.
Conditions
SAADC is disabled after sampling with BURST when multiple channels have been enabled.
Consequences
Current consumption is higher than expected.
Workaround
Execute the following code after disabling SAADC:
volatile uint32_t temp1;
volatile uint32_t temp2;
volatile uint32_t temp3;
temp1 = *(volatile uint32_t *)0x40007640ul;
temp2 = *(volatile uint32_t *)0x40007644ul;
temp3 = *(volatile uint32_t *)0x40007648ul;
*(volatile uint32_t *)0x40007FFCul = 0ul;
*(volatile uint32_t *)0x40007FFCul;
*(volatile uint32_t *)0x40007FFCul = 1ul;
*(volatile uint32_t *)0x40007640ul = temp1;
*(volatile uint32_t *)0x40007644ul = temp2;
*(volatile uint32_t *)0x40007648ul = temp3;
