-===== Other =====
+==== Other ====
+  * IOA11: Only a pull down resitor?
+  * IOA12: Only a test point on the motherboard?
+===== V.Smile Pocket =====
+  * IOA0-IOA11: LCD STN interface
+  * IOA13: LCD backlight control
+  * IOA14: Read as 0 according to notes in V.Smile Motion schematics
+====== Port B ======
+===== ROM and cartridge =====
+  * IOB0: extra address bit for the cartridge port, access second half of ROM
+  * IOB1: Set to 0 to enable cartridge ROM
+  * IOB2: Set to 0 to enable internal ROM
+Note: these can be used with the "External Memory Control" register, in that case they are controlled by the CPU core automatically depending on the address being accessed.
+For example in external address mode 2 or 3 (4 ROMs mode):
+^Pin   ^Address range^
+|IOB0  |100000-1FFFFF|
+|IOB1  |200000-2FFFFF|
+|IOB2  |300000-3FFFFF|
+|ROMCSB|008000-0FFFFF|
+In external address mode 0: ROMCSB is the only one used for the whole range (note: ROMCSB is not wired to anything, so in this area no ROM will be enabled)
+In external mode 1 (2 ROMs mode):
+^Pin   ^Address range^
+|IOB1  |200000-3FFFFF|
+|ROMCSB|008000-1FFFFF|
+Additionally, the end of the address space can also receive RAM (in the cartridge), this is configured separately and different RAM sizes are possible.
+===== Power control =====
+  * IOB3: Labelled "RESTART", not used?
+  * IOB4: "A/D", related to the ADC?
+  * IOB5: Voltage detect (ADC measurement of battery level or power supply)
+  * IOB6: Pulled to ground by the ON button
+  * IOB7: Pulled to ground by the OFF button
+====== Port C ======

+|US English (with standard subtitle)                                         | 1 | 1 | 1 | 1 |  F  |
+The standard English subtitle is "Learning System" in v1.02+ and "TV Learning System" in v1.00.
+Values below 7 have the same behavior as US English in v1.00, except that values below 6 boots to a blinking
+blue VTech logo in white when no cartridge is inserted.
+Note that Italian and the subtitle-less variant of UK English swap places in v1.03.
+IOC4: if 1: show logo animation at boot
+IOC5: currently unknown, maybe LCD/TV detection? Unused in V.Smile motion schematics, test point in older consoles?
