Section 20 Serial IO (SIOF)
20.2.8
This register shows states of SIOF. Each bit of this register becomes interrupt source when 1 is set
to corresponding register of SIIER register.
This register is initialized at power on reset or software reset.
Note: * 0 should be written into these bits. Otherwise the operation is unpredictable.
Bits 15, 11, and 7 to 5—Reserved
Bit 14—Transmit Control Data Ready (TCRDY): This bit displays condition of SITCR
register. SIOF clears when any value is written to SITCR register. This bit becomes effective
when 1 is written to TXE bit of SICTR register. SIOF issues control interrupt if interrupt issuing is
allowed for this bit. Once any data are written to SICTR register with 0 of TCRDY bit, new data is
overwritten to original data and original data of TXD_SIO will be lost.
Note: When using this bit, refer to note 2 in section 20.4, Notes on Use.
Bit 14: TCRDY
0
1
Bit 13—Transmit FIFO Empty (TFEMP): This bit is showing condition, SIOF clear by writing
to SITDR register. This bit becomes effective when 1 is written to the TXE bit of SICTR register.
SIOF issues control interrupt if interrupt issuing is allowed by this bit.
