3.3 Interrupt Functions
The TMP90CM38 has a general-purpose interrupt process-
ing routine for responding to both internal and external inter-
rupt request, and a high-speed micro DMA (HDMA)
processing mode in which the CPU automatically transfers
data.
Immediately after a reset is released, all responses to
interrupt requests are set to the general-purpose interrupt
processing mode.
The high-speed DMA processing mode can be set by
loading a vector value to the DMAV 0/1 register.
Figure 3.3 (1) shows the interrupt response flow.
Figure 3.3 (1). Interrupt Response Flow
When an interrupt request is generated, this is reported to
the CPU via the built-in interrupt controller. If the request is for
a non-maskable interrupt or an enabled maskable interrupt,
the CPU starts interrupt processing. If for a disabled maskable
interrupt, the request is ignored and not received.
If the interrupt is received, the CPU first reads the interrupt
vector from the built-in interrupt controller to determine the
source of the interrupt request.
Next, a check is made as to whether this request is for
general-purpose interrupt processing, micro DMA processing or
high-speed DMA (HDMA) processing, and then the corresponding
processing is performed.
The interrupt vector is read in an internal operation cycle
so the bus cycle becomes a dummy cycle.
