Serial Bus Interface (SBI)
16.2
16.3
The following registers control the serial bus interface and provide its status information for monitoring.
The functions of these registers vary, depending on the mode in which the SBI is operating. For a detailed
description of the registers, refer to "16.4 Control in the I
synchronous 8-bit SIO Mode."
