I(AM, cache hit ratio): Program resides in FRAM. Data resides in SRAM. Average current dissipation varies with
cache hit-to-miss ratio as specified. Cache hit ratio represents number cache accesses divided by the total number of
FRAM accesses. For example, a 75% ratio implies three of every four accesses is from cache, and the remaining are
FRAM accesses.
I(AM, RAMonly): Program and data reside entirely in RAM. All execution is from RAM. FRAM is off.

(1) All inputs are tied to 0 V or to V_CC. Outputs do not source or sink any current.
(2) Current for watchdog timer clocked by SMCLK included.
f_ACLK = 32768 Hz, f_MCLK = 0 MHz, f_SMCLK = f_DCO at specified frequency, except for 12 MHz: here f_DCO = 24 MHz and f_SMCLK = f_DCO/2.
