Description
Interrupt Vector Control
The IVC field controls if and how the assertion of IACKN (the interrupt
acknowledge pin) will form the interrupt vector for the UART. If 00, no vector will
be presented during an IACKN cycle. The bus will be driven HIGH (0xFF). If the
field contains a 01, the contents of the IVR, Interrupt Vector Register, will be
presented as the interrupt vector without modification.
If IVC = 10, the channel code will replace the LSB of the IVR; if IVC = 11 then a
modified interrupt type and channel code replace the 3 LSBs of the IVR.
Remark: The modified type field IVR[2:1] is:
Interrupt status masking
This bit controls the readout mode of the Interrupt Status Register, ISR. If set,
the ISR reads the current status masked by the IMR, that is, only interrupt
sources enabled in the IMR can ever show a ‘1’ in the ISR. If cleared, the ISR
shows the current status of the interrupt source without regard to the Interrupt
Mask setting.
00 = no interrupt vector
01 = IVR[7:0]
10 = IVR[7:1] + channel code
11 = IVR[7:5] + interrupt type + channel code
10: Receiver without error
11: Receiver with error
01: Transmitter
00: all remaining sources
0 = ISR unmasked
1 = ISR read masked by IMR
