1.11 Controller Working Current Characteristic

Current consumption is a combination of several parameters and factors, including operating voltage, ambient temperature, I/O pin
load, product software configuration, operating frequency, I/O pin turnover rate, program location in memory, and code executed,
etc.
⚫
Maximum current consumption
The micro-controller is in the following conditions ：
◼
All I / O pins are in input mode and are connected to a static level VDD or VSS with no load.
◼
All peripherals are disabled, unless otherwise noted.
◼
The access time of the flash memory is adjusted to the f
period for 18 to 36 MHz, 2 waiting period for over 36 MHz).
◼
The command pre-fetch function is turned on (notes: this parameter must be set before the clock and bus
frequency distribution is set).
◼
When the peripherals are turned on：
Maximum current consumption in operating mode and the data processing code
