INT_CTRL Interrupt control register
Address: 0x09
Type: R/W
Reset: 0x00
Description: The interrupt control register is used to enable the interruption from a system-related
interrupt source to the host.
INT_EN Interrupt enable register
Address: 0x0A
Type: R/W
Reset: 0x00
Description: The interrupt enable register is used to enable the interruption from a system related
interrupt source to the host.
