3.2 RESET
3.2.1 Reset Operation
When reset conditions occur, the MB89630 series of microcontrollers suspend the currently-executing in
struction to enter the reset state. The contents written at the RAM do not change before and after reset.
How ever, if a reset occurs during writing of 16-bit long data, data is written to the upper bytes and may not
be written to lower bytes. If a reset occurs around write timing, the contents of the addresses being written
are not as sured.
When the reset conditions are cleared, the MB89630 series of microcontrollers are released from the reset
state and start operation after fetching the mode data from address FFFDH, the upper bytes of the reset vec
tors from address FFFE
H, and the lower bytes from address FFFFH, in that order. Figure 3.2 shows the flow
chart for the reset operation.
Fig. 3.16 Outline of Reset Operation
Table 3-1 indicates the structure of data to be stored in addresses FFFD
H, FFFEH, and FFFFH.
