180: Routine at 51836

51836: Sound: "180"

Used by the routine at Handler_Bust.
Plays 1-bit PCM speech for the "ONE HUNDRED AND EIGHTY!" announcement.
Sound_180Speech	51836	LD HL,54528	Set a pointer to the speech data in HL to Data_Speech.
	51839	LD DE,2048	Set the data length counter in DE to 2048 bytes.
SpeechProcessByte	51842	LD B,8	Set a counter in B for 8 bits per byte.
SpeechProcessBit	51844	RLC (HL)	Rotate *HL left one position to set the next bit to the carry flag.
Set the speaker bit ON or OFF based on if the currently processed bit is set or not.
	51846	LD A,%00010000	Set the speaker bit to ON.
	51848	JR C,SpeechOutputSample	Jump to SpeechOutputSample if the carry bit is set.
	51850	XOR A	Set the speaker bit to OFF.
Output the sample.
SpeechOutputSample	51851	OUT (254),A	Send A to the speaker.
Introduce a tiny delay.
	51853	LD C,18	Set a delay counter in C.
SpeechDelay_Loop	51855	DEC C	Decrease the delay counter by one.
	51856	JR NZ,SpeechDelay_Loop	Jump back to SpeechDelay_Loop until the delay counter is zero.
	51858	DJNZ SpeechWasteCycles	Decrease the bit counter by one and jump to SpeechWasteCycles until all bits in the current byte have been processed.
Finished with this byte, move onto the next.
	51860	INC HL	Move to the next byte of speech data.
	51861	DEC DE	Decrease the data length counter by one.
	51862	LD A,D	Jump back to SpeechProcessByte until all the bytes have been processed.
	51863	OR E
	51864	JR NZ,SpeechProcessByte
All done, re-enable the interrupts and return.
	51866	EI	Enable interrupts.
	51867	RET	Return.
Minor timing tweaks (probably).
SpeechWasteCycles	51868	NOP	No operation.
	51869	NOP
	51870	NOP
	51871	NOP
	51872	NOP
	51873	JR SpeechProcessBit	Jump to SpeechProcessBit.
