Hello everyone! I have a question about PS/2 keyboard.

1. Freescale MKL27 analog PS / 2 timing to the PS / 2 keyboard to send 0xFF, not 0xFA command; in accordance with the same principle, in STM32 can indeed achieve and PS / 2 keyboard communication.
2. In the boot self-test can not identify the PS / 2 device, but I use the same code in the 51 single chip can indeed be achieved.
I realized the function on other platforms, transplanted to Freescale did not succeed, I would like to ask PS / 2 timing in the end and what? How do I get PS / 2 keyboard boot check on Freescale MKL27, how do I receive PS / 2 keyboard data and send commands to the keyboard?
