Serial Status Register (SxSTA: S1STA, S2STA)
SxSTA is a “Read-only” register. The contents of
this register may be used as a vector to a service
routine. This optimized the response time of the
software and consequently that of the I
2
C-bus.
The status codes for all possible modes of the I
2
C-
bus interface are given Table
54
.
This flag is set, and an interrupt is generated, after
any of the following events occur.
1.
Own slave address has been received during
AA = 1: ack_int
2.
The general call address has been received
while GC(SxADR.0) = 1 and AA = 1:
3.
A data byte has been received or transmitted
in Master Mode (even if arbitration is lost):
ack_int
A data byte has been received or transmitted
as selected slave: ack_int
A stop condition is received as selected slave
receiver or transmitter: stop_int
Data Shift Register (SxDAT: S1DAT, S2DAT)
SxDAT contains the serial data to be transmitted
or data which has just been received. The MSB
(Bit 7) is transmitted or received first; that is, data
shifted from right to left.
4.
5.
Table 53. Serial Status Register (SxSTA)
Table 54. Description of the SxSTA Bits
Note: 1. Interrupt Flag Bit (INTR, SxSTA Bit 5) is cleared by Hardware as reading SxSTA register.
2. I
C Interrupt Flag (INTR) can occur in below case. (except DDC2B Mode at SWENB=0)

General Call Flag

STOP
Stop Flag. This bit is set when a STOP condition is received
5
INTR
(1,2)
Interrupt Flag. This bit is set when an I2C Interrupt condition is requested
4
TX_MODE
Transmission Mode Flag.
This bit is set when the I2C is a transmitter; otherwise this bit is reset
3
BBUSY
Bus Busy Flag.
This bit is set when the bus is being used by another master; otherwise, this bit is reset
2
BLOST
Bus Lost Flag.
This bit is set when the master loses the bus contention; otherwise this bit is reset
1
/ACK_REP
Acknowledge Response Flag.
This bit is set when the receiver transmits the not acknowledge signal
This bit is reset when the receiver transmits the acknowledge signal
0
SLV
Slave Mode Flag.
This bit is set when the I2C plays role in the Slave Mode; otherwise this bit is reset
