RESET
A high-low transition on RST clears all internal registers except the three error counters; a resync is
initiated until RST returns high. RST must be held low on system power-up and when switching to/from
the hardware mode. Following reset, the host processor should update all on-chip registers to establish
desired operating modes.
HARDWARE MODE
An on-chip hardware control mode simplifies preliminary system prototyping and serves applications
which do not require the features of the serial port. Tying SPS low disables the serial port, clears all
internal register locations except those shown below, and redefines pins 14 through 18 as mode control
inputs. The mode control inputs establish device operational characteristics as shown in Table 8. The
hardware mode simplifies device retrofit into existing applications where control interfaces are designed
with discrete logic.
