Description
Transmit Reset
0: Does not reset transmit operation
1: Resets transmit operation
•
•
This bit is automatically cleared by SIOF after
completes a reset, to be always read as 0.
Receive Reset
0: Does not reset receive operation
1: Resets receive operation
•
•
This bit is automatically cleared by SIOF after
completes a reset, to be always read as 0.
This bit setting becomes valid immediately. This bit
should be cleared to 0 before setting the register to
be initialized.
When the 1 setting for this bit becomes valid, the
SIOF immediately sets transmit data from the
SIOFTXD pin to 1, and initializes the transmit data
register and transmit-related status. The following
are initialized.
 SITDR
 SITCR
 Transmit FIFO write pointer
 TCRDY, TFEMP, and TDREQ bits in SISTR
This bit setting becomes valid immediately. This bit
should be cleared to 0 before setting the register to
be initialized.
When the 1 setting for this bit becomes valid, the
SIOF immediately disables reception from the
SIOFRXD pin, and initializes the receive data
register and receive-related status. The following
are initialized.
 SIRDR
 SIRCR
 Receive FIFO read pointer
 RCRDY, RFFUL, and RDREQ bits in SISTR
