DESCRIPTION
When writing “1” to this register bit, it set the correspondent interrupt request
bit.
When reading this register, it returns the interrupt request bit status:
0: It is not the bit that causes the interrupt request on primary interface
1: It is the bit that causes the interrupt request on primary interface
Reset to 0000h
DESCRIPTION
When writing “1” to this register bit, it set the correspondent interrupt request
bit.
When reading this register, it returns the interrupt request bit status:
0: It is not the bit that causes the interrupt request on secondary interface
1: It is the bit that causes the interrupt request on secondary interface
Reset to 0000h
DESCRIPTION
When writing “1” to this register bit, it clears the correspondent interrupt
request mask bit.
When reading this register, it returns the primary Clear IRQ Mask bit status:
0: It allows to clear an interrupt request on primary interface
1: It does not allow to clear any interrupt request on primary interface
Reset to FFFFh
DESCRIPTION
When writing “1” to this register bit, it clears the correspondent interrupt
request mask bit.
When reading this register, it returns the Secondary Clear IRQ Mask bit
status:
0: It allows to clear an interrupt request on secondary interface
1: It does not allow to clear any interrupt request on secondary interface
Reset to FFFFh
