Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
8.17 I/O Interrupt Enable register (IOIntEna)
This register enables the interrupt due to a change in the I/O configured as inputs. If
GPIO[7:4] or GPIO[3:0] are programmed as modem pins, their interrupt generation must
be enabled via IER[3]. In this case, IOIntEna will have no effect on GPIO[7:4] or
GPIO[3:0].
8.18 I/O Control register (IOControl)
Remark: As I/O pins, the direction, state, and interrupt enable of GPIO are controlled by
the following registers: IODir, IOState, IOIntEna, and IOControl. The state of CD, RI, DSR
pins will not be reflected in MSR[7:5] or MSR[3:1], and any change of state on these three
pins will not trigger a modem status interrupt (even if enabled via IER[3]), and the state of
the DTR pin cannot be controlled by MCR[0].
As modem CD, RI, DSR pins, the status at the input of these three pins can be read from
MSR[7:5] and MSR[3:1], and the state of the DTR pin can be controlled by MCR[0]. Also,
if modem status interrupt bit is enabled, IER[3], a change of state on RI, CD, DSR pins will
trigger a modem interrupt. The IODir, IOState, and IOIntEna registers will not have any
effect on these three pins.

IOIntEna register bits description

Description
7:0
IOIntEna
Input interrupt enable.
0 = a change in the input pin will not generate an interrupt
1 = a change in the input will generate an interrupt

reserved
These bits are reserved for future use.
3
SRESET
Software Reset. A write to this bit will reset the device. Once the
device is reset this bit is automatically set to logic 0.
2
GPIO[3:0] or
RIB, CDB,
DTRB, DSRB
This bit programs GPIO[3:0] as I/O pins or as modem pins.
0 = I/O pins
1 = GPIO[3:0] emulate RIB, CDB, DTRB, DSRB
1
GPIO[7:4] or
RIA, CDA,
DTRA, DSRA
This bit programs GPIO[7:4] as I/O pins or as modem pins.
0 = I/O pins
1 = GPIO[7:4] emulate RIA, CDA, DTRA, DSRA
0
IOLATCH
Enable/disable inputs latching.
0 = input value are not latched. A change in any input generates an
interrupt. A read of the input register clears the interrupt. If the input
goes back to its initial logic state before the input register is read,
then the interrupt is cleared.
1 = input values are latched. A change in the input generates an
interrupt and the input logic value is loaded in the bit of the
corresponding input state register (IOState). A read of the IOState
register clears the interrupt. If the input pin goes back to its initial
logic state before the interrupt register is read, then the interrupt is
not cleared and the corresponding bit of the IOState register keeps
the logic value that initiates the interrupt.
