UART Receive Data or infrared receive data. Normal receive data
input must idle at logic 1 condition. The infrared receiver idles at
logic 0.
UART Request-to-Send (active low) or general purpose output. This
output must be asserted prior to using auto RTS flow control, see
EFR[6], MCR[1] and IER[6]. This pin is not available in the 24-
QFN package.
UART Clear-to-Send (active low) or general purpose input. It can
be used for auto CTS flow control, see EFR[7], MSR[4] and IER[7].
This input should be connected to VCC when not used. This pin is
not available in the 24-QFN package.
UART Data-Terminal-Ready (active low) or general purpose output.
This pin is not available in the 24-QFN and 28-QFN packages.
UART Data-Set-Ready (active low) or general purpose input. This
input should be connected to VCC when not used. This input has no
effect on the UART. This pin is not available in the 24-QFN and
28-QFN packages.
UART Carrier-Detect (active low) or general purpose input. This
input should be connected to VCC when not used. This input has no
effect on the UART. This pin is not available in the 24-QFN and
28-QFN packages.
UART Ring-Indicator (active low) or general purpose input. This
input should be connected to VCC when not used. This input has no
effect on the UART. This pin is not available in the 24-QFN and
28-QFN packages.
Crystal or external clock input. This input is not 5V tolerant.
Crystal or buffered clock output. This output may be use to drive a
clock buffer which can drive other device(s).
Power-Save (active high). This feature isolates the L580’s data bus
interface from the host preventing other bus activities that cause
higher power drain during sleep mode. See Sleep Mode with Auto
Wake-up and Power-Save Feature section for details. This pin has
an internal pull-down resistor in the 48-TQFP package. The 32-QFN
package does not have this pull-down resistor.
Intel or Motorola Bus Select. This pin has an internal pull-up resistor
in the 48-TQFP package. The 32-QFN package does not have this
resistor.
When 16/68# pin is at logic 1, 16 or Intel Mode, the device will oper-
ate in the Intel bus type of interface.
When 16/68# pin is at logic 0, 68 or Motorola mode, the device will
operate in the Motorola bus type of interface.
