NOTE
Typical operational current for 60-MHz devices can be estimated from Figure 6-1. For Idd
current alone, subtract the current contribution of non-existent peripherals. For example,
to compute the current of F2801-60 device, the contribution by the following peripherals
must be subtracted from Idd : ePWM4/5/6, eCAP3/4, eQEP2, SPI-C/D, SCI-B, eCAN-B.
