mode in Wait mode by setting the EPM or WAITM bit in the Flash_CR1 register.
6. Tested in production.
7. Oscillator bypassed (HSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the HSE consumption
(I
DD HSE
) must be added. Refer to Ta ble 31.
8. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption
(I
