Added posted writes (read after writes) to effect the change immediately for channel confiuration and channel enable register
Disable the channel to purge receieve data in TX_ONLY mode transfer otherwise rx data will get affected by the next immediate RX_ONLY mode transfer
Wait for the EOT bit to be set after last byte has been loaded to TX shift register in the the TX_ONLY mode.This ensures TX data has been completely shifted out
Disable the channel in RX_ONLY mode before reading the last data from RXX register to prevent the SPI slave to transmit next word
