Remaining DRAM output
DRAM write terminated. (An RZP pulse is output when there is an overflow or a shock.)
Data contact point detection complete signal: low→ high: detection complete. (DRAM write start).
DRAM write enable signal input: high: write enable.
Pause signal input: high: pause.
Shared function pin that functions either as a 16M DRAM address output (AD10) or as a DRAM control
signal (CAS2) used when 8M of DRAM (two 4M DRAM chips) is used. The function is switched by the
DRAM selection pins MR1 and MR2.
Remaining DRAM alarm output: low: memory low.
C2F shock detect pause signal input: low: pause shock detection.
