PSEL[3:0] — Priority Select Bits
5.4 Interrupts
5-8
The IRVNE control bit allows internal read accesses to be available on the external
data bus during factory testing or emulation. Refer to SECTION 4 OPERATING
MODES AND ON-CHIP MEMORY for more information.
These bits select one interrupt source to be elevated above all other I-bit-related
sources and can be written to only while the I bit in the CCR is set (interrupts disabled).
The MCU has 18 interrupt vectors that support 22 interrupt sources. The 19 maskable
interrupts are generated by on-chip peripheral systems. These interrupts are recog-
nized when the global interrupt mask bit (I) in the condition code register (CCR) is
clear. The three non-maskable interrupt sources are illegal opcode trap, software in-
terrupt, and XIRQ pin. Refer to Table 5-4, which shows the interrupt sources and vec-
tor assignments for each source.
