Teensy 3.2 current, might upgrade in the future.
Im a little confused when browsing through schematics and source code.
Interfacing with an external static 64k RAM. 16 address bits and 8 data bits.
I would like to do full byte or word write to the pins. I haven't connected the RAM yet I'm flexible on which pins to use.
And thats kinda my problem, which pins/ports? PORTA seems use by a few other things. On PORTB I can only find PTB0,1,2,3,16,17 and 18, where did the rest go?
PORTC has PTC0-11, perfect for writing bytes with + a few bits to control some other stuff.
As for my 16 adress bits, PORTD won't help me right?
TLDR;
How do I do byte writes to C0-7? SSRC?
There isn't 16 bits mapped and easily accessible anywhere right? So, just have to set the bits one by one?
