+Primitive M0110 Library for AVR
+==============================
+
+
+Signaling
+---------
+CLOCK is always from KEYBOARD. DATA are sent with MSB first.
+
+1) IDLE: both line is high.
+ CLOCK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ DATA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+2) KEYBOARD->HOST: HOST reads bit on rising edge.
+ CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~
+ DATA ~~~~~~~~~~~~X777777X666666X555555X444444X333333X222222X111111X000000X~~~~~~~
+ <--> 160us(clock low)
+ <---> 180us(clock high)
+
+3) HOST->KEYBOARD: HOST asserts bit on falling edge.
+ CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~
+ DATA ~~~~~~|_____X777777X666666X555555X444444X333333X222222X111111X000000X~~~~~~~
+ <----> 840us(request to send by host) <-> 80us(hold DATA)
+ <--> 180us(clock low)
+ <---> 220us(clock high)
+
+
+Protocol
+--------
+COMMAND:
+ Inquiry 0x10 get key event
+ Instant 0x12 get key event
+ Model 0x14 get model number(M0110 responds with 0x09)
+ bit 7 1 if another device connected(used when keypad exists?)
+ bit4-6 next device model number
+ bit1-3 keyboard model number
+ bit 0 always 1
+ Test 0x16 test(ACK:0x7D/NAK:0x77)
+
+KEY EVENT:
+ bit 7 key state(0:press 1:release)
+ bit 6-1 scan code
+ bit 0 always 1
+ To get scan code, use ((bits&(1<<7)) | ((bits&7F))>>1).
