12 | Description | ||
13 | ----------- | ||
14 | |||
15 | Support is provided through the sysfs files "eeprom" and "pio". CRC checking | ||
16 | during memory accesses can optionally be enabled/disabled via the device | ||
17 | attribute "crccheck". The strong pull-up can optionally be enabled/disabled | ||
18 | via the module parameter "w1_strong_pullup". | ||
19 | |||
20 | Memory Access | ||
21 | |||
22 | A read operation on the "eeprom" file reads the given amount of bytes | ||
23 | from the EEPROM of the DS28E04. | ||
24 | |||
25 | A write operation on the "eeprom" file writes the given byte sequence | ||
26 | to the EEPROM of the DS28E04. If CRC checking mode is enabled only | ||
27 | fully alligned blocks of 32 bytes with valid CRC16 values (in bytes 30 | ||
28 | and 31) are allowed to be written. | ||
29 | |||
30 | PIO Access | ||
31 | |||
32 | The 2 PIOs of the DS28E04-100 are accessible via the "pio" sysfs file. | ||
33 | |||
34 | The current status of the PIO's is returned as an 8 bit value. Bit 0/1 | ||
35 | represent the state of PIO_0/PIO_1. Bits 2..7 do not care. The PIO's are | ||
36 | driven low-active, i.e. the driver delivers/expects low-active values. | ||
