ENTI
Enable I2C 14-bits Timer Counter:
0: Disable 14-bits Timer Counter count.
1: Enable 14-bits Timer Counter count. After enable ENTI and ENSI, the 14-bit
counter will be counted. When SI flag of I2C is set, the counter will stop to
count and 14-bits Timer Counter will be cleared.
1
DIV4
I2C Timer Counter clock source divide function:
0: The 14-bits Timer Counter source clock is Fosc clock.
1: The 14-bits Timer Counter source clock is divided by 4.
0
TIF
The I2C Timer Counter count flag:
0: The 14-bits Timer Counter is not overflow.
1: The 14-bits Timer Counter is overflow. Before enable I2C Timer (both ENTI,
ENSI = [1,1]) the SI must be cleared. If I2C interrupt is enabled. The I2C
interrupt service routine will be executed. This bit is cleared by software.

ENS1
0: Disable I2C Serial Function. The SDA and SCL output are in a high impedance
state. SDA and SCL input signals are ignored, I2C is not in the addressed slave
mode or it is not addressable, and STO bit in I2CON is forced to “0”. No other bits
are affected. P1.2 (SCL) and P1.3 (SDA) may be used as open drain I/O ports.
1: Enable I2C Serial Function. The P1.2 and P1.3 port latches must be to logic 1.
5
STA
The START flag.
0: The STA bit is reset, no START condition or repeated START condition will be
generated.
1: The STA bit is set to enter a master mode. The I2C hardware checks the status of
I2C bus and generates a START condition if the bus is free. If bus is not free, then
I2C waits for a STOP condition and generates a START condition after a delay. If
STA is set while I2C is already in a master mode and one or more bytes are
transmitted or received, I2C transmits a repeated START condition. STA may be
set any time. STA may also be set when I2C interface is an addressed slave
mode.
