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
