Be a code detective. The assembler has a directive called BANKSEL, $$bank select,$$ that makes

it easier to move from bank to bank without having to look up the location of different SFRs$.$

The following assembly code initializes PortB to be an output, and then writes a $1($HIGH$)$

to PORTB$<0>.$

ORG $0$x$0008$

BANKSEL TRISB

CLRF TRISB

BANKSEL PORTB

BSF PORTB, $0$

The opcodes produced by these statements are as follows $($all numbers are hex$)$:

Location Opcode

$--------------$

$00081683$

$00091303$

$000$A $0186$

$000$B $1283$

$000$C $1303$

$000$D $1406$

The column on the left is the location in program memory. Use the table of opcodes and other

information in the PIC$16$F$87/88$ Datasheet $($on the course website$)$ to decode the above opcodes and determine which specific PIC instructions are created by the BANKSEL directive.

You will also need to consult the register file map to figure out which SFRs are affected.
