4.2 Initial Settings After Initial Reset
The CPU internal registers are initialized as follows
during initial reset.
Table 4.2.1 Initial settings
*
Reset exception processing loads the preset
values stored in 0 bank, 000000H–000001H into
the PC. At the same time, 01H of the NB initial
value is loaded into CB.
Initialize the registers which are not initialized at
initial reset using software.
Since the internal RAM and display memory are
not initialized at initial reset, be sure to initialize
using software.
The respectively stipulated initializations are done
for internal peripheral circuits. If necessary, the
initialization should be done using software.
For initial value at initial reset, see the sections on
the I/O memory map and peripheral circuit
descriptions in the following chapter of this
Manual.
4.3 Programming Note
All the interrupts including NMI are masked until
any value is written to both addresses "00FF00H"
and "00FF01H".
To release the interrupt mask, data must be written
to addresses 00FF00H and 00FF01H in the initial
routine. Write "0" to bit 7 and bit 6 in 00FF00H and
do not change the value after writing. Any value
can be written from bit 5 to bit 0 in 00FF00H and all
bits in 00FF01H.
