Pin No.
Reset : Active high
Initializes or Reinitializes the W3100A-LF. Asserting this
pin will force a reset process to occur, which will result in
all internal registers reinitializing to their default and all
strapping options are reinitialized.
For complete reset function, this pin must be asserted low
for at least 10us. Refer to W3100A-LF datasheet for
further detail regarding reset.
Reset : Active low
Reset RTL8201BL chip. For complete reset function this
pin must be asserted low for at least 10ms.
Mode Select : These pins select MCU interface and
operating mode. Since each pin is pull-down internally,
clocked mode (the default mode) is selected when these
pins are not connected.
Refer to W3100A-LF datasheet for further detail regarding
mode select
External clock : supplementary clock used for external
clocked mode.
In external clocked mode, W3100A-LF uses this clock to
interface with MCU.
Refer to W3100A-LF datasheet for further detail regarding
external clock.
