ADPCM_FRAME_SIZE
Address: 0xBD (189)
Type: R/W
Software Reset: 0x13
Hardware Reset: 0x00
The ADPCM frame size may be adjusted to match a trade-off between the bitrate overhead and the frame
length. The frame size (in bytes) is calculated as follow:
FRAME size = (ADPCM_FRAME_SIZE * 90) +108
The frame starts with a 12 bytes header:
ADPCM_INT_CFG
Address: 0xBE (190)
Type: R/W
Software Reset: 0x0B
Hardware Reset: 0x00
Using this register the ADPCM interrupt capability can be properly configured. INTL0 - INTL6 Interrupt
Length he interrupt length can be programmed, using this bits, from 0 up to 128 system clock cycles
GPIO_CONF
Address: 0xBF (191)
Type: R/W
Software Reset: 0x00
Hardware Reset: 0x00
This register controls how data are strobed on the GPIO interface.
GISP: GPIO Strobe Polarity in INPUT mode
GOSP: GPIO Strobe Polarity in OUTPUT mode
– 6 bytes for DVI algorithm
– 96 bytes for G726 pack algorithms
