+/***************************************************************************
+
+    Roland MB63H114 Multiple Address Counter
+
+    The multiplexed outputs of eight 13-bit counters internal to this
+    64-pin QFP CMOS gate array are used to play percussion samples.
+
+    The on-chip clock generator must be externally strapped by connecting
+    SCO1 (36) to CLK0 (37) to obtain the standard 1.6 MHz master clock.
+    This is divided to produce 100, 50, 25 and 12.5 kHz outputs on A (3),
+    B (5), C (7) and D (4). These outputs are normally connected to the
+    XCK0–XCK7 inputs (56–57, 59–64), upper address lines and chip selects
+    of sample mask ROMs, and 40H151 multiplexers and demultiplexers, but
+    may also be used to drive other circuits.
+
+    The XST0–XST7 (38–41, 44–47) counter start inputs, strobed with XSTA
+    (50), are normally connected to CPU address outputs rather than the
+    data bus, perhaps due to long setup/hold requirements. All these are
+    specified as active low.
