+ * 01/25/2007 1.1 Bug is Fixed in the Indirect Mode
+ * : Memory mapping error
+ * ---------- ------- ------------------------------------------------
+ * 01/08/2008 1.2 Modification of Socket Command Part
+ * : Check if the appropriately performed after writing Sn_CR
+ *
+ * Modification of SPI Part
+ * : SPI code changed by adding 'spi.h'.
+ * : Change control type for SPI port from byte to bit.
+ * ---------- ------- ------------------------------------------------
+ * 01/15/2008 1.3 Bug is Fixed in the pppinit() fuction.
+ * : do not clear interrupt value, so fixed.

+ * Modification of ISR
+ * : Do not exit ISR, if there is interrupt.
+ * ---------- ------- ------------------------------------------------
+ * 03/21/2008 1.4 Modification of SetMR() function
+ * : Use IINCHIP_WRITE() function in Direct or SPI mode.
