ISP1582 sample code

PCI Sample code :

• 先unlockdeive : *(0x7C) = 0xAA37; 由suspend mode喚醒，對任何register 動作前要對 unlock register寫入AA37。
• testmodereg 寫入0x10 : *(0x84) = 0x10 ; FORCEFS - force Full Speed.
• mode register, clear SOFTCT (soft-connect) ，也就是將D+ pullup 移除(變成full speed)。
• 對interrupt register 寫入0xFFFFFF，將所有interrupt source 清除。 *(0x18) = 0xFFFFFFFF.
  interrupt register register 代表目前產生interrupt的原因，對該bit寫入1可以將該source clear。

Register Reading: - debug 才需要

• 對scratch register寫入0xAA55，讀出確認OK。
• Interrupt Config (0x10)
• Interrupt mast L.H (x014, 0x16)
• Interrupt register L.H (0x18, 0x1A)
• DMA config (0x38)
• DMA counter L.H (0x34,0x36)
• Current Frame Number (0x74)
• Mode (0x0C)
• Address (0x00)

Install ISR

Read Chip ID 0x70.74.76

開始connect USB:

 Address Enable : *(0x00) = 0x80;
Mode :  *(0x0C) =  0x08 | 0x01 | 0x80 | 0x200; GLINTENA, SOFTCT, CLKAON, 0x200
Test : *(0x84) = 0x00;  exit test mode
IntConfig: (0x10) = 0x40 | 0x10 | 0x04; cdbgmod_as,ddbgmodin_a, ddbgmodout_asy,
                                         control interrupt :  on ack,stall

                                         out interrupt : ack and stall
IntEnableLow :*(0x14) = 0x0001 | 0x0008 | 0x0010 | 0x0020 | 0x0100 | 0x0080

                                         ep2rx, ep2tx.
IntEnableHi : *(0x16) = 0x00;

Config Endpoint
先將7個endpoint的tx,rx type 都設為0
