29.3.8 Status
Register
(SISTR)
SISTR is a 16-bit readable/writable register that shows the SIOF state. Each bit in this register
becomes an SIOF interrupt source when the corresponding bit in SIIER is set to 1.

This bit is always read as 0. The write value should
always be 0.

Transmit Control Data Ready
0: Indicates that a write to SITCR is disabled
1: Indicates that a write to SITCR is enabled
•
If SITCR is written when this bit is cleared to 0,
SITCR is over-written and the previous contents of
SITCR are not output from the SIOF_TXD pin.
•
This bit is valid when the TXE bit in SITCR is set to
1.
•
This bit indicates a state of the SIOF. If SITCR is
written, the SIOF clears this bit.
•
If the issue of interrupts by this bit is enabled, an
SIOF interrupt is issued.

0: Indicates that transmit FIFO is not empty
1: Indicates that transmit FIFO is empty
•
This bit is valid when the TXE bit in SICTR is 1.
•
This bit indicates a state; if SITDR is written, the
SIOF clears this bit.
•
If the issue of interrupts by this bit is enabled, an
SIOF interrupt is issued.
