1.11 The Serial Interface Bus (SIB)
W65C134S
March 1, 2000

The Serial Interface Bus (SIB) is configured as a token passing Local Area Network, and is intended for
inter-chip communications in parallel processing applications. The Serial Interface Bus has four pins
associated with its use: CHIN CHOUT, SDAT, and SCLK (see Section 2.19 for more information). The SIB
has seven (7) registers associated with its use: STATE, SR0, SR1, SR2, SR3, SCSR, and BAR.
1.11.1 The STATE Register
The STATE register is a read-only register that provides the host processor with the timing state of
the SIB (see Figure 1-13 for more information on activities during each timing state). The STATE
register is the decoded output of a "state machine" that counts up from 0 to 37 and then back to 0 on
positive transitions of SCLK. Only one decoded output is asserted at a time. STATE has the same
value at the same time in all devices and is used to synchronize message transfer. It is reset to State 0
upon system RESET.
STATE is normally read only during manufacturing test. A read of the state register can produce
invalid results if the SCLK is not synchronous with the processor clock. When the SCLK is enabled
on the chip with its MPU, it is always synchronized with the SIB.
