RI2/PWM1CLK
I
Ring Indicator.
This active low input is for the UART ports. A handshake
signal notifies the UART that the telephone ring signal is detected by the
modem. The CPU can monitor the status of the RI_n signal by reading bit 6 of
the Modem Status Register (MSR). An RI_n signal states the change from low
to high after the last MSR read sets bit 2 of the MSR to a “1”. If bit 3 of the
Interrupt Enable Register is set, the interrupt is generated when RI_n changes
state.
Note:
Bit 6 of the MSR is the complement of RI_n.
PWM Timer1 Clock.
This pin is PWM timer1 external clock input when SB
register C0h bit2 is 1 (PINs for PWM).
Data Terminal Ready.
This is an active low output for the UART port. A
handshake output signal signifies the modem that the UART is ready to
establish data communication link. This signal can be programmed by writing
to bit 0 of Modem Control Register (MCR). The hardware reset will clear the
DTR_n signal to be inactive during the loop-mode operation.
PWM Timer1 Output.
This pin is PWM timer1 output when SB register C0h
bit2 is 1 (PINs for PWM).
COM2 TX Status.
This pin will be high when COM2 is trnamitting.
PWM Timer2 Gate.
This pin is PWM timer2 gate mask when SB register C0h
bit2 is 1 (PINs for PWM).
