Interrupt Functions

Interrupt
Communi- The interrupt subroutine is executed when data is
cations received in the receive buffer. All data received is
interrupts stored in the receive buffer
The interrupt subroutine is executed when a speci-
fied character is received in the receive buffer. (Data
beyond the specified character is also received in the
buffer.) (See note 1.)
The interrupt subroutine is executed when a speci-
fied number of bytes is received in the receive buffer.
(Data beyond the specified number of bytes is also
received in the buffer.) (See note 1.)
The interrupt subroutine is executed when a speci-
fied final character is received in the receive buffer
after a specified start character. (The string of char-
acters between the start character and final charac-
ter remains in the buffer. Data after the specified final
character is also received in the buffer.) (See note 1.)
The interrupt subroutine is executed when a speci-
fied number of characters is received in the receive
buffer after a specified start character. (The character
string from the specified start character to the speci-
fied number of characters remains in the receive
buffer, and the data after the specified number of
characters is also received in the receive buffer.)
(See note 1.)
Key The interrupt subroutine is executed when a certain
interrupts key signal is input. (See note 3.)
PC Specified PC interrupt number interrupt subroutines
interrupts are executed by interrupts from the IOWR(#CC00)
instruction or IR/CIO words allocated to the ASCII
Unit in the PC. (See note 4.)
I/O Allocations: PC interrupts are triggered by the IR/
CIO words allocated to the ASCII Unit: IR/CIO n bit
04.
PC interrupt number is set in IR/CIO n + 2 bits 00 to
07.
IOWR(#CC00): Triggers a PC interrupt by sending
data.
Timer The interrupt subroutine is executed repeatedly each
interrupts time the timer times out (interval time). (Once exe-
cuted, the subroutine is repeated until TIME OFF is
specified.)
On alarm The subroutine interrupt is executed when the timer
interrupts times out (one-shot timer). (No repetition after the ini-
tial execution.)
Scheduled The interrupt subroutine is executed at a specified
interrupts time.
Error The interrupt subroutine is executed when an error
interrupts occurs.

ON TIMER 300 GOSUB
A subroutine branch to the GOSUB

after this command is executed; the
subroutine branch is then repeated
each 30 seconds. Timer: 0 to

ON ALARM 300 GOSUB
A subroutine branch to the GOSUB
line number will occur once only, 30
seconds after this command is
executed.
