Backplane Output Bit Rate Registers (BOBRR0-31)
Address 012Dh to 014Ch
Thirty-two Backplane Output Bit Rate Registers allow the bit rate for each individual stream to be set to 2, 4, 8 or
16 Mb/s.These registers may be overridden by setting 32Mb/s mode in the control register, in which case, backplane
streams 0-15 will operate at 32Mb/s and backplane streams 16-31 will be unused. The
BOBRR
registers are
configured as follows:
Table 47 - Backplane Output Bit Rate Register (BOBRRn) Bits
Table 48 - Backplane Output Bit Rate (BOBRR) Programming Table
13.14
Memory BIST Register
Address 014Dh
The Memory BIST register enables the self-test of chip memory. Two consecutive write operations are required to
start MBIST. The first with only Bit 12 (LV_TM) set High (i.e. 1000h), the second with Bit 12 maintained High but with
the required start bit(s) set High.
The
MBISTR
register is configured as follows:
