5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
Rev. 04 — 6 October 2008
Description
Address 0 select bit. Internal registers address selection.
Address 1 select bit. Internal registers address selection.
Address 2 select bit. Internal registers address selection.
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 reflected 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
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
MCR[7]. A logic 0 (GND) on CLKSEL will latch a logic 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
