82C237
FIGURE 13. MEMORY-TO-MEMORY TRANSFER
NOTE: For 16-bit mode, 82C237 only. In 8-bit mode this signal is always high impedance three-stated. Waveform shown is for a 16-bit memory-to-memory
transfer. For an 8-bit transfer in 16-bit mode, DWLE will go high at least TASS before the falling edge of ADSTB in S2, then low TAHS after the falling
edge of ADSTB, and will remain low until the next ADSTB where the cycle is repeated.
FIGURE 14. READY
NOTE: READY must not transition during the specified setup and hold times.
