8.5 Interrupt Poll Register
Interrupt Poll Register
In Normal Mode, UART’s internal registers can be accessed through nCS and UART’s
GISR (Global Interrupt Status Register) is used for checking 8 UART channel’s interrupt
status. GISR is the same register as IPR in this case.
IPR access Option Register through nOPT control signal in MIO mode and GISR access
UART internal Register through nCS or nUART signal. GISR and IMR are same region
and IN16C1058 provides different methods of accessing them.
