21 / 226 page  TMP88CS38/CM38A/CP38A 2007-09-12 88CS38-21 1.5 Interrupt Controller The TMP88CS38/CM38A/CP38A has a total of 17 interrupt sources; 6 externals and 11 internals. Multiple interrupts with priorities are also possible. Two of the internal sources are pseudo non-maskable interrupts; the remainder are all maskable interrupts.

After a DI instruction is executed. b. When an interrupt is accepted, IMF is automatically cleared to “0”. However to enable nested interrupts, change EF and/or IL before setting IMF to “1” (to enable interrupts). If the individual enable flags (EF) and interrupt latches (IL) are set under conditions other than the above, the proper operation cannot be guaranteed. |
