When bits 0, 1, 2, or 3 are set to logic 1, a Modem Status interrupt is generated if bit 3 of the
Interrupt Enable Register is set.

Change in clear-to-send (DCTS) indicator
DCTS indicates that the CTS# input has changed state since the
last time it
was read by the CPU. When DCTS is set (autoflow control is not
enabled and the modem status interrupt is enabled), a modem
status interrupt is generated. When autoflow control is enabled
(DCTS is cleared), no interrupt
is generated:
1: Change in state of CTS# input since last read
0: No change in state of CTS# input since last read
0
LPC: r/w
1
Change in data set ready (DDSR) indicator
DDSR indicates that the DSR# input has changed state since the
last time it
was read by the CPU. When DDSR is set and the modem status
interrupt is
enabled, a modem status interrupt is generated:
1: Change in state of DSR# input since last read
0: No change in state of DSR# input since last read
0
LPC: r/w
2
Trailing edge of the ring indicator (TERI) detector
TERI indicates that the RI# input to the chip has changed from a
low to a high level. When TERI is set and the modem status
interrupt is enabled, a modem status interrupt is generated. Not
supported.
0
LPC: r/w
3
Change in data carrier detect (DDCD) indicator
DDCD indicates that the DCD# input to the chip has changed
state since the
last time it was read by the CPU. When DDCD is set and the
modem status
interrupt is enabled, a modem status interrupt is generated. Not
supported.
0
LPC: r/w
