corresponding flag can be individually enabled or disabled by the enable bits in SFRs IEN0, IEN1, and
IEN2. Some of the 10 sources are multiplexed in order to expand the number of interrupt sources.
1.7.5
The 80515 core provides 10 interrupt sources with four priority levels. Each source has its own request
flag(s) located in a special function register (TCON, IRCON, and SCON). Each interrupt requested by the
These will be described in more detail in the respective sections.
External interrupts are the interrupts external to the 80515 core, i.e. signals that originate in other
parts of the 73S1217F, for example the USB interface, USR I/O, RTC, smart card interface, analog
comparators, etc. The external interrupt configuration is shown in Figure 9.
