3.2 Host DSP Read and Write Procedures
The modem DSP RAM consists of four memory banks : data RAM real, data RAM imaginary, coefficient
RAM real, and coefficient RAM imaginary. When accessing the main RAM the desired RAM access code
needs to be written into ADR
X
( X = 1,2 ), with 1 and 2 referring to RAM access 1 and 2 respectively. The
RAM location is specified by bits 0-6 and bit 7, when zero, specifies a real ( XRAM ) RAM location, and
when one, an imaginary ( YRAM ) RAM location. The BRT
X
(
X
= 1,2 ) bit controls whether the data access
takes place at the baud rate or the sampling rate. The CRAM
X
controls whether the data RAM
( CRAM
X
is reset ) or the coefficient RAM ( CRAM
X
is set ) is accessed. In parallel data mode ( PDME
is set 1 ) only RAM access associated with RAM Address1 is available since register 10h is used as the
transmit/receive data buffer ( DBFR ).
