When SIO1 is in a master mode serial clock frequency is
determined by the clock rate bits CR2, CR1 and CR0. The various
bit rates are shown in Table 25.
The data shown in Table 25 do not apply to SIO1 in a slave mode. In
the slave modes, SIO1 will automatically synchronize with any clock
frequency up to 400kHz.

NOTE:
1. These bit rates are for “fast–mode” I2C bus applications and cannot be used for bit rates up to 100 kbit/sec.
Serial status register S1STA
S1STA is a read only register.
The contents of the status 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.
