Interrupt Control Register
NOTES:
b7
1. To rewrite the interrupt control registers, do so at a point that does not generate the interrupt request for that
2. When the BYTE pin is low and the processor mode is memory expansion or microprocessor mode, set bits
3. This bit can only be reset by writing 0 (do not write 1).
4. If bits IFSR10 to IFSR15 in the IFSR1 register are 1 (both edges), set the POL bit in registers INT0IC to INT5IC
5. Set the POL bit in the S3IC register to 0 (falling edge) when the IFSR00 bit in the IFSR0 register = 1 and the
6. Use the IFSR17 bit in the IFSR1 register to select.
7. Use the IFSR16 bit in the IFSR1 register and the IFSR00 bit in the IFSR0 register to select.
