Serial Status Register (S1STA)

S1STA is a read-only register. The contents of this register may be used as a vector to a service routine. This optimizes

the response time of the software and consequently that of the I2C-bus. The status codes for all possible modes of the

I2C-bus interface is given in Table 29. The register has only a valid vector to a service routine if the SI bit of the S1CON
