CRC checking -during memory accesses can optionally be enabled/disabled via the device -attribute "crccheck". The strong pull-up can optionally be enabled/disabled -via the module parameter "w1_strong_pullup". - -Memory Access - - A read operation on the "eeprom" file reads the given amount of bytes - from the EEPROM of the DS28E04. - - A write operation on the "eeprom" file writes the given byte sequence - to the EEPROM of the DS28E04. If CRC checking mode is enabled only - fully aligned blocks of 32 bytes with valid CRC16 values (in bytes 30 - and 31) are allowed to be written. - -PIO Access - - The 2 PIOs of the DS28E04-100 are accessible via the "pio" sysfs file. - - The current status of the PIO's is returned as an 8 bit value. Bit 0/1 - represent the state of PIO_0/PIO_1. Bits 2..7 do not care. The PIO's are - driven low-active, i.e. the driver delivers/expects low-active values. |
