Pin to port mapping reference for Teensy 3.6?

Hi, I'm looking for a pin to port mapping reference for the Teensy 3.6. Like, say I use this code:

PORTA = 0x80;

Which pins on the Teensy correlate to which bits on what the CPU considers to be port A?

I need to wire up a 512 KB parallel SRAM chip to gain access to more memory, and access must be very fast. Ideal code would be something like:

Code:
void writeSRAM(uint32_t address, uint8_t value) {
    PORTA = (uint8_t)address;
    PORTB = (uint8_t)(address >> 8);
    PORTC = (uint8_t)(address >> 16);
    PORTD = value;
}

Where ports A, B, C connect to the address lines of the SRAM and port D connects to the data lines.

Thanks!
