Arduino for STM32

Is 'STM32F103C8' 'digitalWrite' and 'digitalRead' possible in FAST mode?

hello.
[Status]
1. MCU: STM32F103C8
2. CORE1: https://github.com/rogerclarkmelbourne/Arduino_STM32


In the case of Arduino (AVR), there are the following libraries.

'digitalWrite' Operates 'digitalRead' quickly.


Is it possible to operate ‘Fast mode’ through ‘CORE1’?
If anyone knows, please help.

google search for "stm32 bsrr" and learn how to use that
e.g.
https://gist.github.com/iwalpola/6c36c9 ... 0a118571ca

and for *really fast*, stm32 spi can do like > 20 Mbps, not for novices
