### another simple test - set stack to h7FFFC, store 4 numbers on stack (only 2
### will really get written to memory, other 2 will remain in r0 and r1),
### then pop all the numbers and write them to h57574
## set sp to h7FFFC (actually, lowest bit is assumed 0 and not stored there)
# 7777 FFFF F
# bits 19:11 of h7FFFC are 0111 1111 1
