+Maple Native (STM32F103ZE) pin definitions, by GPIO bank.
+
+Source: ST DOC ID 14611, Datasheet for STM32F103xC, STM32F103xD,
+STM32F103xE, Table 5, pp. 30--35.
+
+Some peripherals and extra functionality with less/no libmaple
+relevance (at time of writing) are given in "Other" following each
+bank's main table. Non-default alternate functions are not listed. If
+wirish will/does remap the pin's main function after reset, the main
+function is listed under "Other".
+
+This document was prepared carefully and is believed to be complete
+and correct, but the final arbiter of truth is the ST datasheet.
+
+*** NB: UART 4 and 5 are NOT USART (columns are labeled appropriately).
