The subroutine starting at $198D ends with a RTS, and thus cannot be accessed from any other bank, because it would leave remnants on the stack (JSL pushes three byte on the stack, RTS only pulls two). So, this is an adapter for accesses from other banks. Other banks jump here (pushes a long address on stack), this jumps to $198D (pushes the word address "$198C" on stack, the RTS at the end of $198D pulls the word-sized address and the RTL leads back where it originally came from.

C1/1A09 set bit according to Accumlator
The value in A must be between 0 and 7. According to that number, a value is loaded into A; the value has one bit set, the number of that bit is the same as the original value. So, if the original value is #$03, the resulting value is #$08 = #%0000.1000 (bit 4 is set), if the original value is #$10 = #%0001.0000 (bit 5 is set). Values higher than 7 make the subroutine consume itself: #$08 --> #$AA, #$09 --> #$BF, #$0A --> #$01 and so on.
