Figure 9. CAN 0 Controller Block Diagram
The TAP controller communicates synchronously with
the host system (bus master) through four digital I/Os:
test mode select (TMS), test clock (TCK), test data
input (TDI), and test data output (TDO). The internal
TAP module consists of several shift registers and a
TAP controller (see Figure 11). The shift registers serve
as transmit-and-receive data buffers for a debugger.

The MAXQ7670 includes a powerful hardware SPI mod-
ule, providing serial communication with a wide variety
of external devices. The SPI port on the MAXQ7670 is a
fully independent module that is accessed through soft-
ware. This full 4-wire, full-duplex serial bus module sup-
ports master and slave modes. The SPI clock
