Consider the following code snippet: BSF TRISA,4 BCF TRISB,3 BTFSC PORTA,4 BRA HERE BSF PORTB,3 BCF PORTB,3 BRA HERE HERE Explain what the program does when Bit 3 of PORTA is High Bit 3 of PORTA goes Low Table 4-8: Single-Bit (Bit-Oriented) Instructions for PIC18 Instruction BSFfileReg,bit BCF fileReg.bit BTG fileReg,bit BTFSC fileReg,bit BTFSS fileReg,bit Functioin Bit Set fileReg (set the bit: bit 1 Bit Clear fileReg (clear the bit: bit = 0 Bit Toggle fileReg (complement the bit Bit test fileReg, skip if clear (skip next instruction if bit 0 Bit test fileReg, skip if set (skip next instruction if bit 1
