Output from the internal oscillator for the crystal. If a crystal is not used, X1 must
be left unconnected.

I
Input to the internal oscillator from the crystal or a clock

EMU4/SHZ
1
I
Shutdown high impedance. When active, EMU4/SHZ shuts down the SMJ320C30
and places all pins in the high-impedance state. EMU4/SHZ is used for board-level
testing to ensure that no dual-drive conditions occur. CAUTION: A low on SHZ
corrupts SMJ320C30 memory and register contents. Reset the device with SHZ
high to restore it to a known operating condition.

I = input, O = output, Z = high-impedance state, NC=No Connect
For GB package
§ S=SHZ active, H = HOLD active, R = RESET active
NOTES: 1. CVSS,VSS,IVSS are on the same plane.
2. The connections specified for the reserved pins must be followed. For best results, 18-k--22-k pullup resistors are
recommended. All 5-V supply pins must be connected to a common supply plane, and all ground pins must be connected to a
common ground plane.
