Carrier Detect (active LOW).
These inputs are associated with
individual UART channels A through D. A logic LOW on these pins
indicates that a carrier has been detected by the modem for that
channel. The state of these inputs is re铿俥cted in the modem status
register (MSR).
Clock Select.
CLKSEL selects the divide-by-1 or divide-by-4
prescalable clock. During the reset, a logic 1 (V
CC
) on CLKSEL
selects the divide-by-1 prescaler. A logic 0 (GND) on CLKSEL selects
the divide-by-4 prescaler. The value of CLKSEL is latched into
MCR[7] at the trailing edge of RESET. A logic 1 (V
CC
) on CLKSEL will
latch a 0 into MCR[7]. A logic 0 (GND) on CLKSEL will latch a 1 into
MCR[7]. MCR[7] can be changed after RESET to alter the prescaler
value. This pin is associated with LQFP80 and PLCC68 packages
only. This pin is connected to V
CC
internally on LQFP64 package.
