Issue details are:
1. when requested as multiple of 32 bytes, but more than 32 bytes, e.g., 64 bytes, only one 32-byte interrupt transmit happens and rest are ignored.
2. when requested as non-multiple of 32 bytes, but more than 32 bytes, e.g., 70 bytes. In this case, when Spi_SetupEB is first called, there is no actual limit with the transmission, but when Spi_SetupEB is called second time, program can not transmit.
