What's New:
- a2suprterm: Initialize RAM/ROM mapping mode on start [Roman Donchenko]. Initialize m_bC800IsRAM on start (#12872). Fixes unpredictable RAM/ROM mapping in C800 range if not set by writing to C0n2 or C0n4 first. Allow RAM/ROM mapping control via C0Bx reads. Allow mapping control via C0Bx reads (#12876). C0B2, C0B4 and C0B6 react to both reads and writes according to the manual [Roman Donchenko].
- bml3: Standardize read/write function names [Angelo Salese]. Hookup BAUD SEL [Robbbert].
- cmi_01a: Add filters [Olivier Galibert].

- f2mc16: Created devices for the onboard analogue to digital converter, clock generator, interrupt controller/Extended intelligent I/O service, I/O port, Programmable Pulse Generator, reload timer and UART. CPU core exposes the RMW line for onboard devices. Log messages will contain the address of the start of the instruction, rather than the next byte the CPU is about to fetch. Added INT9/INT addr16 & INT addr24 software interrupt instructions. Fixed INCW @RWx & DECW @RWx instruction length Added missing fetch of immediate value in MOV @RWx + RW7, #imm8. Rewrote Tomy Prin-C keyboard handling and pen to use new onboard devices, substantially increasing the reload timer 0 frequency as it's now correctly waiting for 0x7530 underflows with reload = 0x37f at startup [smf].
- h8: Increased timeout in namco_csz1 ROM to stop it timing out, the H8 is either running too fast or the SUB CPU is running too slow. Configured Crisis Zone gun to match game defaults & default to namco_csz1 JVS I/O board [smf].
- h8_sci: Disable logging by default & don't log debugger reads. Only start sending data via DMA if transmitter is enabled. Clear TEND when sending data via DMA. TDRE, RDRF, ORER, PER and FER flags can be cleared to 0 only if they have first been read while set to 1. Only set TEND when there is no more data to send. Receiver is started only on high to low rxd in asynchronous mode, when receiving and sending in synchronous mode when data is sent, or continuously when receiving without sending in synchronous mode. Set rx status to idle when stopping clock in rx_async_step(). Remove double invert when calculating parity in rx_async_step(). Remove redundant check for synchronous mode in rx_async_step() [smf].

- kn5000: Add 2 newly dumped data ROMs (#12902). With this we now get a good-looking "CPU communication" error screen during boot [Felipe Corr�a da Silva Sanches].
- m68000: Renamed variables used for restarting instructions to reduce potential confusion. Rename m_instruction_restart to m_can_instruction_restart to clearly distinguish from m_restart_instruction (#12869) [Adam Billyard]. Don't emulate byte smearing for the 68040, and fix disabling the FPU for the 68030 [R. Belmont]. Implemented FETOX, FETOXM1, FTWOTOX and FTENTOX instructios [Minsu Kwon].
- mc6843: Fixes and improvements: Make Seek Track Zero issue step pulses when the track 0 sensor is off rather than on. Enable IRQ output from device (bml3 software needs this). Issue Status Sense Request in PC I/O mode, not DMA mode. Raise Seek Error if STZ command doesn't end at track 0. Add settle timeout for head unload after certain commands. Enhance logging messages but hide them behind logmacro compilation switches [AJR].
