- Fairchild F3853 SRAM interface with integrated interrupt

+Fairchild F3853 SMI, F3851 PSU, F3856 PSU, F38T56 PSU
- This chip is a timer shift register, basically the same as in the
- F3851.
+This device only emulates the I/O, interrupt, timer functions. Not the
+low-level ROMC signals.
- Based on a datasheet obtained from www.freetradezone.com
+F3853: Static memory interface with integrated interrupt controller and timer.
- 8-bit shift register:
- Feedback in0 = !((out3 ^ out4) ^ (out5 ^ out7))
- Interrupts are at 0xfe
- 0xff stops the register (0xfe is never reached)
+The timer is an 8-bit linear feedback shift register:
+Feedback in0 = !((out3 ^ out4) ^ (out5 ^ out7))
+Interrupts are at 0xfe
+0xff stops the register (0xfe is never reached)
+
+F3851: Program Storage Unit, same timer and interrupt controller as F3853,
+but has 2 I/O ports instead of a programmable interrupt vector.
+
+F3856/F38T56 Program Storage Unit: similar interrupt controller, timer
+is more versatile, a simple downcounter instead of shift register.
+
+TODO:
+- emulate at lower level and place this stuff into devices/cpu/f8 folder
+- interrupt priority pin
+- 3856/38T56 timer pulse counter mode, event counter mode

+ * XC1702L 2,097,152
+ * XC1704L 4,194,304
+ *
+ * The input C̅E̅ and CLK lines have not been explicitly implemented; these are
+ * assumed to be asserted as expected before/during data read. The effect of
+ * C̅E̅O̅ can be obtained by connecting the cascade_r callback to the data_r of
+ * the cascaded device and resetting all devices when needed.
+ *
+ * This implementation assumes the input data is stored least-significant bit
+ * first; i.e. the first bit read out of the device is held in the LSB of the
+ * first byte of the memory region. This convention matches at least one
+ * dumping device tested.
