B-II-2-4 EPSON S1C33L03 FUNCTION PART
Trap Table
Table 2.1 shows the trap table in the C33 Core. Refer to the "S1C33000 Core CPU Manual" for details of
exceptions and Section II-5 in this manual, "ITC (Interrupt Controller)", for interrupts.
Serial interface Ch.2 and Ch.3 interrupts share the trap table for port input interrupts and 16-bit timer interrupts.
Refer to Section III-8, "Serial Interface", for details of the settings.
