need help for APR6008 SPI interface

[Jerson]

I think it is quite straight forward. Anyway, here goes. Unchecked, untested, use at your own risk and consequence

/***********************************************************************\
		APR48000 voice record/playback IC routines
\***********************************************************************/


' Send a command to the APR48000
'       APR_Cmd is the APR Opcode
'	APR_Adr has the parameter for the opcode
'	Send order is Msb-Lsb
'	   First the Cmd (Lower 6 bits), then Adr (Lower 15 bits)
'	PWRUP (4) (0x2)
'	REC   (9)
'	PLAY  (D)
'	FWD   (3)
'	STOP  (6)

APR_cs         var  PORTA.0  ' define your own
APR_di         var  PORTA.1   ' define your own
APR_clk        var  PORTA.2   ' define your own

APR_Cmd     var  byte
APR_Adr       var  word
BitCnt:          var  byte


CommandAPR:
        APR_Cmd = APR_Cmd << 3
        APR_Adr = APR_Adr << 1
	APR_cs = 0;

        for BitCnt = 0 to 5
		APR_di = APR_Cmd.7
		APR_clk = 1;
                APR_Cmd = APR_Cmd << 1         ' remove the bit we transferred
		APR_clk = 0;
        next

        for BitCnt = 0 to 15
		APR_di = APR_Adr.15  'unsure of this instruction
		APR_clk = 1
		APR_Adr <<= 1                            ' remove the address bit transferred
		APR_clk = 0
        next

	APRcs = 1;
}
