(1) Typical parameters as seen at room temperature including function call overhead, with all peripherals off.
(2) The on-chip flash memory is in an erased state when the device is shipped from TI. As such, erasing the flash memory is not required
prior to programming, when programming the device for the first time. However, the erase operation is needed on all subsequent
programming operations.
