TX_MODE
General Call flag
GC = 1 if the General Call address of 00h was received when
SIOE is in Slave mode, and GC is cleared by a START or
STOP condition on the bus. If the SIOE is in Master mode
when GC = 1, the Bus Lost condition exists, and BLOST = 1.
STOP flag
STOP = 1 while SIOE detects a STOP condition on the bus
when in Master or Slave mode.
Interrupt flag
INTR is set to 1 by any of the five I
above. INTR must be cleared by firmware.
Transmission Mode flag
TX_MODE = 1 whenever the SIOE is in Master-Transmitter or
Slave-Transmitter mode. TX_MODE = 0 when SIOE is in any
receiver mode.
Bus Busy flag
BBUSY = 1 when the I
SIOE when a START condition exists on the bus and BBUSY
is cleared by a STOP condition.
Bus Lost flag
BLOST is set when the SIOE is in Master mode and it looses
the arbitration process to another Master device on the bus.
Not Acknowledge Response flag
While SIOE is in Transmitter mode:
– After SIOE sends a byte, ACK_RESP = 1 whenever the
– After SIOE sends a byte, ACK_RESP = 0 whenever the
Note: If SIOE is in Master-Transmitter mode, and ACK_RESP
= 1 due to a Slave-Transmitter not sending an Acknowledge, a
STOP condition will not automatically be generated by the
SIOE. The STOP condition must be generated with
S1CON.STO = 1.
Slave Mode flag
SLV = 1 when the SIOE is in Slave mode. SLV = 0 when the
SIOE is in Master mode (default).
