Interrupts
The W741E20X provides five internal interrupt sources (Divider 0, Timer 0, Timer 1, serial I/O) and two
external interrupt sources (
INT
, port RC). Vector addresses for each of the interrupts are located in
the range of program memory (ROM) addresses 004H to 020H. The flags IEF, PEF, and EVF are used
to control the interrupts. When EVF is set to "1" by hardware and the corresponding bits of IEF and
PEF have been set by software, an interrupt is generated. When an interrupt occurs, all of the
interrupts are inhibited until the EN INT or MOV IEF, #I instruction is invoked. The interrupts can also
be disabled by executing the DIS INT instruction. When an interrupt is generated in hold mode, the
hold mode will be released momentarily and interrupt subroutine will be executed. After the RTN
instruction is executed in an interrupt subroutine, the
μ
C will enter hold mode again. The operation flow
chart is shown in Figure 14. The control diagram is shown below.
