(1)

Low-power modes are not supported if the internal voltage regulator is disabled.

(2)

VREG wake up = thalt-normal (see Table 5-4).

(3)

Flash pump sleep = minimum time for which the flash pump is in sleep mode before it enters standby mode = 20

µs. The flash pump

sleep to standby counter must be programmed such that the (counter value X wake-up clock source period) is at least 20

µs.

(4)

Flash pump standby = minimum time for which the flash pump is in standby mode before it enters active mode = 1

µs. The flash pump

standby2active counter must be programmed such that the (counter value X wake-up clock source period) is at least 1

µs.

NOTE

The flash banks will wake up in parallel with the flash pump. The flash banks can wake up

faster than the flash pump and therefore the overall flash module wake-up time is determined

by the pump wake-up time.
