Section 19 Interrupt Controller (INTC)
RCMI: Compare-match interrupt
ROVI: Refresh counter overflow interrupt
H-UDI: High-performance use debug interface
GPIOI: I/O port interrupt
DMTE0–DMTE7: DMAC transfer end interrupts
DMAE: DMAC address error interrupt
Notes: 1. Interrupt priority levels can only be changed in the SH7750S or SH7750R. In the
SH7750, the initial values cannot be changed.
2. SH7750R only
19.3 Register Descriptions
19.3.1 Interrupt Priority Registers A to D (IPRA–IPRD)
Interrupt priority registers A to D (IPRA–IPRD) are 16-bit readable/writable registers that set
priority levels from 0 to 15 for on-chip peripheral module interrupts. IPRA to IPRC are initialized
to H'0000 and IPRD is to H'DA74 by a reset. They are not initialized in standby mode.
