^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) Support is provided through the sysfs files "eeprom" and "pio". CRC checking
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) during memory accesses can optionally be enabled/disabled via the device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) attribute "crccheck". The strong pull-up can optionally be enabled/disabled
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) via the module parameter "w1_strong_pullup".

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) Memory Access
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 	A read operation on the "eeprom" file reads the given amount of bytes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 	from the EEPROM of the DS28E04.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 	A write operation on the "eeprom" file writes the given byte sequence
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 	to the EEPROM of the DS28E04. If CRC checking mode is enabled only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 	fully aligned blocks of 32 bytes with valid CRC16 values (in bytes 30
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 	and 31) are allowed to be written.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) PIO Access
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 	The 2 PIOs of the DS28E04-100 are accessible via the "pio" sysfs file.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 	The current status of the PIO's is returned as an 8 bit value. Bit 0/1
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) 	represent the state of PIO_0/PIO_1. Bits 2..7 do not care. The PIO's are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 	driven low-active, i.e. the driver delivers/expects low-active values.
