Intr_status_REG (QSPI) Register Description
Register Name | Intr_status_REG |
---|---|
Offset Address | 0x0000000004 |
Absolute Address | 0x00FF0F0004 (QSPI) |
Width | 32 |
Type | mixedMixed types. See bit-field details. |
Reset Value | 0x00000104 |
Description | Interrupt Status |
This register is set when the described event occurs and the interrupt is enabled in the mask register. When any of these bits are set the interrupt output is asserted high. In the default configuration, these bits are all cleared simultaneously by reading this register, though this may be configured for an individual write-one-to-clear scheme. Software Driver name: XQSPIPS_SR
