Section 19 Interrupt Controller (INTC)
19.3.6 Interrupt Mask Clear Register 00 (INTMSKCLR00) (SH7750R Only)
The interrupt mask clear register 00 (INTMSKCLR00) clears the masking of individual interrupt
requests. INTMSKCLR00 is a 32-bit write-only register.

Bit 31 to 0⎯Interrupt Mask Clear: Each bit selects whether or not to clear the masking of the
interrupt source that corresponds to that bit. For the correspondence between the bits and interrupt
sources, see section 19.3.7, Bit Assignments of INTREQ00, INTMSK00, and INTMSKCLR00
(SH7750R Only).
