105 / 923 page  Rev. 2.00, 09/03, page 75 of 890 Vector fetch Internal processing Prefetch of first program instruction φ Internal address bus RES Internal read signal Internal write signal Internal data bus (16 bits wide) (1) (2) (2) (3) (1) Address of reset vector (H'0000) (2) Start address (contents of reset exception handling vector address) (3) First instruction of program Figure 4.4 Reset Sequence (Mode 6) 4.2.3 Interrupts after Reset If an interrupt is accepted after a reset but before the stack pointer (SP) is initialized, PC and CCR will not be saved correctly, leading to a program crash. To prevent this, all interrupt requests, including NMI, are disabled immediately after a reset. The first instruction of the program is always executed immediately after the reset state ends. This instruction should initialize the stack pointer (example: MOV.L #xx:32, SP). |
