S1STA contains a status code which reflects the status
of SIO1 and the I2C bus. The three least significant bits
are always zero. The five most significant bits contains
the status code. There are 12 possible status code. When
S1STA contains F8h, no relevant state information is
available and no serial interrupt is requested. A valid
status code is available in S1STA one machine cycle
after SI is set by hardware and is still present one
machine cycle after SI has been reset by software.
Table 7. to Table 9. give the status for the operating
modes and miscellaneous states.
