Detailed Description of Registers
Serial Channel (HSIO)
HSC0BUF
HSC0EN
As channels 0 to 3 have same register set, only channel 0 is described here.

Enable Register
TX/ RX Buffer Register
It specifies HSIO operation. When HSIO is to be used, be sure to enable HSIO by setting "1" to
this register before setting any other registers of the HSIO module. When HSIO operation is
disabled, the clock will not be supplied to the HSIO module except for the register part and thus
power consumption can be reduced. If HSIO is enabled once and then disabled, any register setting
is maintained.
Always reads "0."
