Comparison with C200H-ASC02
Appendix B
Flags/Control Bits Software Restart Bit Yes No
Read Bit and PC Interrupt Bit Uses the Write Bit. The Read Bit and the PC
Interrupt Bit are different.
ASCII Busy Flag Changes status when the
PC interrupt is generated. Does not change when the
PC interrupt is generated.
Instead, the PC Interrupt Fail
Flag changes if the PC
interrupt fails.
Interrupts Multiple interrupts Yes. If an XXX ON command
occurs, or another interrupt
is generated while executing
an interrupt subroutine, the
executing interrupt
subroutine is stopped, and
the next interrupt subroutine
is branched to. No. If another interrupt is
generated while executing
an interrupt subroutine, the
next subroutine is executed
after the first interrupt
subroutine execution is
completed. The interrupt will,
however, stop executing
immediately when an ON
ERROR interrupt is
generated.
Multiple interrupts are
executed in the order that
they were generated. The next interrupt subroutine
is executed according to
order of priority.
Executing interrupts Even if a BASIC interrupt
occurs while a command is
being executed, it will not
branch into the interrupt
subroutine. Branching will
only occur after the
command has been
executed. When a BASIC interrupt
occurs while a command is
being executed, the interrupt
subroutine will be executed,
but only once.
Processing speed Execution time depending on
destination of GOSUB and
GOTO commands. Changes according to the
distance from the current line
to the destination. Same time for all
destinations.
Commands RND command Random number generator logic is different.
WAIT command Timer does not stop while
interrupt subroutine is being
executed. Timer stops while interrupt
subroutine is being
executed.
PRINT USING command Display will change depending on the USING format.

Saving to/reading from ROM Uses the LOAD command to
read from EEPROM. Reads from /writes to the
flash ROM and user memory
(RAM) using the ROMLOAD
and ROMSAVE commands.
