-Internal of HHKB pro
-=====================
-HHKB pro has MCU and some chips on separate two PCBs.
-
-Controller PCB
---------------
-    M38K07M4    Renesas MCU with USB function
-                http://documentation.renesas.com/eng/products/mpumcu/rej03b0192_38k0ds.pdf

-Keyswitch PCB
--------------
-    HC4051      Analog Multiplexer: select a row line.
-                http://www.ti.com/lit/ds/schs122j/schs122j.pdf
-    LS145       BCD Decoder: select a column line.
-                http://www.ti.com/lit/ds/symlink/sn74ls145.pdf
-    BU9831      Non-volatile electronic potentiometer: for calibration?
-                https://www.spezial.com/doc/rohm-a/bu9831.pdf
-    TP1683/4    Capacitive Sensing controller: no datasheet available.

-Connector Cable
----------------
-Two PCBs are connected by 15 lines(13 in case of Pro2).
-Vcc and GND use 3(2) lines each, other lines are for keyboard signaling.

-    NOTE: Probably HYS changes threshold for upstroke and makes hysteresis in the result.
-    NOTE: HYS should be given High(1) when previous KEY state is Low(0).
-    NOTE: 1KOhm didn't work as pullup resistor on KEY. AVR internal pullup or 10KOhm resistor was OK.
-    NOTE: JP has two HC4051(Z2,Z3) and line 5, 6 and 7 are connected to both of them.

-Signals charts
---------------
-    While pressing space bar, watched HHKB Pro original controller signals by logic analyzer.
-    Row and column is looping between 0-7 each for selecting a key.
-    A key is scaned every about 15ms, so scan rate is 66Hz.
-
-    (HHKB_chart1.jpg)
-
-    Space bar locate at ROW:3 COL:7. A key is selected by HC4051(C,B,A) and LS145(C,B,A).
-    Key state can be read on TP1684(4/KEY) while asserting low on LS145(D).

-    NOTE: JP scans twice fast as Pro/Pro2 does. So Pro/Pro2 scans 8x8 matrix in 15.4ms while JP scans 16x8 in that time.
