Industrial-temperature Single Chip Ethernet Controller with General Processor Interface
General Purpose 3~1
When the correspondent bit of General Purpose Control Register is 1, the value of
the bit is reflected to pin GEPIO3-1
When the correspondent bit of General Purpose Control Register is 0, the value of
the bit to be read is reflected from correspondent pins of GEPIO3-1
The GEPIOs are mapped to pins GEPIO3 to GEPIO1 respectively
General Purpose 0
The value of the bit is the output to pin GEPIO0
This bit also defines the power down status of Internal PHYceiver. Driver needs to
clear this bit by writing “0” when it wants internal PHYceiver to be power up. This
default value can be programmed by strap pin GPIO4 or EEPROM. Please refer to
the EEPROM description
RX SRAM Write Pointer Address High Byte (25H)
CHIP Revision
When set, the LED pins act as led mode 1.
When cleared, the led mode is depending on strap pin or EEPROM setting.
