21 / 54 page  SECOND CASE CM = 0: ACCESS TO AUXILIARY MEMORY Microprocessor writes Auxiliary Memory to transmit Primitives for each TX C/I channel and to transmit Bytes of message for each TX MON channel. Microprocessor reads Auxiliary memory to recover Primitive received by each RX C/I channel and to re- cover the message received by each RX MON channel. TX Command Indicate channel - Selected by Destination Register (DST) CM CR5 CR4 CR3 CR2 CR1 CR0 R/W 0 - - - - PT1 PT0 R/W = 1 Read auxiliary memory After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the bits of the register have the following meaning: CR5/CR2 Not used PT0/1 Primitive trasmitted PT1 PT0 Status 00 Primitive has not been transmitted yet 01 Primitive has been transmitted once 10 Primitive has been transmitted twice 11 Primitive has been transmitted more than twice. R/W = 0 Write auxiliary memory. CR0/CR5 not used RX Command Indicate channel - Selected by Destination Register (DST) CM CR5 CR4 CR3 CR2 CR1 CR0 R/W 0 - - - - OVR PR R/W = 1 Read auxiliary memory After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the bits of the register have the following meaning: CR5/CR2 Not used OVR Overrun OVR = 1. The previous primitive has not been read by the microprocessor. PR Primitive Received. PR = 1. The primitive has been received once PR = 0. The primitive has been received twice or more. The primitive is in Source Register. R/W = 0 Writing auxiliary memory. CR0/CR5 not used STLC5460 21/54 |
