Part 3 OCCS
3.1 Overview
The On-Chip Clock Synthesis (OCCS) module allows designers using an internal relaxation oscillator, an
external crystal, or an external clock to run 56F8000 family devices at user-selectable frequencies up to
32MHz. For details, see the OCCS chapter in the 56F802x and 56F803x Peripheral Reference Manual.

Test Clock Input — This input pin provides a gated clock to
synchronize the test logic and shift serial data to the JTAG/EOnCE
port. The pin is connected internally to a pull-up resistor. A Schmitt
trigger input is used for noise immunity.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TCK.
Test Mode Select Input — This input pin is used to sequence the
JTAG TAP controller’s state machine. It is sampled on the rising
edge of TCK and has an on-chip pull-up resistor.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TMS.
Note:
Always tie the TMS pin to V
