DESCRIPTION
0: PI7C9X110 can initiate an interrupt request when the correspondent
request bit is set
1: PI7C9X110 cannot initiate any interrupt request even though the
correspondent request bit is set
Reset to FFFFFFFFh
DESCRIPTION
0: PI7C9X110 can initiate an interrupt request when the correspondent
request bit is set
1: PI7C9X110 cannot initiate any interrupt request even though the
correspondent request bit is set
Reset to FFFFFFFFh
DESCRIPTION
When writing “1” to this register bit, it clears 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 clears 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
