Interrupt Enable Register - Epson S1C88650 Technical Manual

5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Interrupt and Standby Status)

5.14.3 Interrupt enable register

The interrupt enable register has a 1 to 1 corre-
spondence with each interrupt factor flag and
enable/disable of interrupt requests can be set.
When "1" is written to the interrupt enable register,
an interrupt request is enabled, and is disabled
when "0" is written.

Table 5.14.3.1 Interrupt enable registers and interrupt factor flags
This register also permits reading, thus making it
possible to confirm that a status has been set.
At initial reset, the interrupt enable registers are set
to "0" and shifts to the interrupt disable status.
Table 5.14.3.1 shows the correspondence between
the interrupt enable registers and the interrupt
factor flags.
