Intrpt_Mask (I2C) Register Description
| Register Name | Intrpt_Mask |
|---|---|
| Offset Address | 0x0000000020 |
| Absolute Address |
0x00FF020020 (I2C0) 0x00FF030020 (I2C1) |
| Width | 16 |
| Type | roRead-only |
| Reset Value | 0x000002FF |
| Description | Interrupt Mask |
Each bit in this register corresponds to a bit in the interrupt status register. If bit i in the interrupt mask register is set, the corresponding bit in the interrupt status register is ignored. Otherwise, an interrupt is generated whenever bit i in the interrupt status register is set. Bits in this register are set through a write to the interrupt disable register and are cleared through a write to the interrupt enable register. All mask bits are set and all interrupts are disabled after reset. Interrupt mask register has the same format as the interrupt status register.
