Consider the following prior to a 68000 hardware reset D0 5

Consider the following prior to a 68000 hardware reset: [D0] = $507112F3, [A5] = SF211A520, [SR] = $8200 What are the contents of D0, A5, and SR after hardware reset?

Solution

Reset is applied only on power-up and total and irrepairable system collapse.
RESET has the highest priority basing on other hardware exceptions.
[SR] $2700 (S=1, T=0 and interrupt mask level set to 7)
[SSP] [$0000] (initialize Supervisor Stack with the first element in the vector table)
[PC] [$0004] (Initialize PC with the second element in the vector table)
[D0] [$000000000]
[A5] [$000000000]

Resume execution at the position pointed by PC
