Chip Reset

The Chip Reset command resets the TLC in the same way as an
external reset pulse.  The System Controller bit is also cleared.
The TLC is reset to the following conditions:

•

The local pon message is set and the interface functions are
placed in their idle states.

•

All bits of the SPMR are cleared.

•

The EOI bit is cleared.

•

All bits of the AUXRA, AUXRB, and AUXRE are cleared.

•

The Parallel Poll Flag and RSC local message are cleared.

•

The contents of the ICR is set to eight (F3 set to 1; F2, F1, and
F0 set to 0).

•

The TRM0 bit and the TRM1 bit are cleared.

The interface functions are held in their idle states until released by
an Immediate Execute pon command.  Between these commands,
the TLC unitable bits may be programmed to their desired states.
