RDBF0: Ch.0 receive data buffer full (D0) / Serial I/F Ch.0 status register (0x401E2)
RDBF1: Ch.1 receive data buffer full (D0) / Serial I/F Ch.1 status register (0x401E7)
RDBF2: Ch.2 receive data buffer full (D0) / Serial I/F Ch.2 status register (0x401F2)
RDBF3: Ch.3 receive data buffer full (D0) / Serial I/F Ch.3 status register (0x401F7)
Indicates the status of the receive data register (buffer).
Read "1": Buffer full
Read "0": Buffer empty
Write: Invalid
RDBFx is set to "1" when the data received in the shift register is transferred to the receive data register (receive
operation completed), indicating that the received data can be read out. This bit is reset to "0" when the data is read
out.
At initial reset, RDBFx is set to "0" (buffer empty).
TXEN0: Ch.0 transmit enable (D7) / Serial I/F Ch.0 control register (0x401E3)
TXEN1: Ch.1 transmit enable (D7) / Serial I/F Ch.1 control register (0x401E8)
TXEN2: Ch.2 transmit enable (D7) / Serial I/F Ch.2 control register (0x401F3)
TXEN3: Ch.3 transmit enable (D7) / Serial I/F Ch.3 control register (0x401F8)
Enables each channel for transmit operations.
Write "1": Transmit enabled
Write "0": Transmit disabled
Read: Valid
When TXENx for a channel is set to "1", the channel is enabled for transmit operations. When TXENx is set to "0",
the channel is disabled for transmit operations.
Always make sure the TXENx = "0" before setting the transfer mode and other conditions.
At initial reset, TXENx is set to "0" (transmit disabled).
RXEN0: Ch.0 receive enable (D6) / Serial I/F Ch.0 control register (0x401E3)
RXEN1: Ch.1 receive enable (D6) / Serial I/F Ch.1 control register (0x401E8)
RXEN2: Ch.2 receive enable (D6) / Serial I/F Ch.2 control register (0x401F3)
RXEN3: Ch.3 receive enable (D6) / Serial I/F Ch.3 control register (0x401F8)
Enables each channel for receive operations.
Write "1": Receive enabled
Write "0": Receive disabled
Read: Valid
When RXENx for a channel is set to "1", the channel is enabled for receive operations. When RXENx is set to "0",
the channel is disabled for receive operations.
Always make sure the RXENx = "0" before setting the transfer mode and other conditions.
At initial reset, RXENx is set to "0" (receive disabled).
