Transmit Circular Buffers One and Zero (Pages 9 and A)
Page 09H, addresses 10000 to 11111 contain the 16 bytes of transmit circular buffer zero (TxB0.0 to TxB0.15
respectively). This feature is functional only in processor and controller modes.
The transmit circular buffers are not cleared by the RST function, nor are they cleared by the RESET function.
Page 0AH, addresses 10000 to 11111 contain the 16 bytes of transmit circular buffer one (TxB1.0 to TxB1.15
respectively). This feature is functional only in processor and controller modes.
Receive Circular Buffers One and Zero (Pages B and C)
Page 0BH, addresses 10000 to 11111 contain the 16 bytes of receive circular buffer zero (RxB0.0 to RxB0.15
respectively). This feature is functional only in processor and controller modes.
Page 0CH, addresses 10000 to 11111 contain the 16 bytes of receive circular buffer one (RxB1.0 to RxB1.15
respectively). This feature is functional only in processor and controller modes.

Transmit Bits 7 to 0. This byte is transmitted on a time slot selected by the TBUF1 bit of the
appropriate per time slot control word. n = 0 to 15 and represents a byte position in Transmit Cir-
cular Buffer zero (TxB1).
Receive Bits 7 to 0. This byte is received from a time slot selected by the RBUF0 bit of the
appropriate per time slot control words. n = 0 to 15 and represents a byte position in receive
circular buffer zero (RxB0).
Receive Bits 7 to 0. This byte is received from a time slot selected by the RBUF1 bit of the
appropriate per time slot control words. n = 0 to 15 and represents a byte position in receive
circular buffer one (RxB1).
Transmit Bits 7 to 0. This byte is transmitted on a time slot selected by the TBUF0 bit of the
appropriate per time slot control word. n = 0 to 15 and represents a byte position in Transmit
Circular Buffer zero (TxB0).
