9.3.3.3 80C51XA
The Philips 80C51XA microcontroller family supports an 8- or 16-bit multiplexed bus that
can have burst cycles. Address bits A[3:0] are not multiplexed, while A[19:4] are
multiplexed with data bits D[15:0] in 16-bit mode. In 8-bit mode, A[11:4] are multiplexed
with data bits D[7:0].
The 80C51XA can be configured to operate in eight-bit data mode. (shown in Figure 18).
The 80C51XA improves bus throughput and performance by executing Burst cycles for
code fetches. In Burst Mode, address A19-4 are latched internally by the PSD935G2, while
the 80C51XA changes the A3-0 lines to fetch up to 16 bytes of code. The PSD access
time is then measured from address A3-A0 valid to data in valid. The PSD bus timing
and hold time with respect to ALE does not apply.
9.3.3.4 68HC11
Figure 19 shows an interface to a 68HC11 where the PSD935G2 is configured in 8-bit
multiplexed mode with E and R/W settings. The DPLD can generate the READ and WR
signals for external devices.
