4.5 MMC Interrupt Mask Register (MMCIM)
Registers
The MMC interrupt mask register (MMCIM) is used to enable (bit = 1) or disable (bit = 0) status interrupts.
If an interrupt is enabled, the transition from 0 to 1 of the corresponding interrupt bit in the MMC status
register 0 (MMCST0) can cause an interrupt signal to be sent to the CPU.
The MMC interrupt mask register (MMCIM) is shown in Figure 22 and described in Table 10 .
