Register Name: SUPC_FWUTR
Access Type: Read-write
• FWUT: Flash Wake Up Timer
Before waking up the Flash Memory (through the FLASHON bit in SUPC_MR), this field must be correctly set. Refer to the
Electrical Characteristics section of the product datasheet to obtain the wake-up time of the Flash Memory.
FWUT = (Maximum wake-up time of the Flash Memory in µs) x (Maximum Master Clock Frequency during the wake-up of
the Flash Memory in MHz)/ 2.
This number must be rounded up. The value 0 is not allowed.
For example, for a maximum wake-up time of 60 µs, and a maximum MCK frequency of 3 MHz during the wake up, FWUP
is: 60 x 3 / 2 = 90 = 0x5A.
