55 / 121 page  ZL50022 Data Sheet 55 Zarlink Semiconductor Inc. Bit Name Description 15 - 9 Unused Reserved. In normal functional mode, these bits MUST be set to zero. 8STIO_PD_ EN STio Pull-down Enable When this bit is low, the pull-down resistors on all STio pads will be disabled. When this bit is high, the pull-down resistors on all STio pads will be enabled. 7BDH Bi-directional Control for Streams 16-31 6BDL Bi-directional Control for Streams 0-15 5 RBEREN PRBS Receiver Enable When this bit is low, all the BER receivers are disabled. To enable any BER receivers, this bit MUST be high. 4 TBEREN PRBS Transmitter Enable When this bit is low, all the BER transmitters are disabled. To enable any BER transmitters, this bit MUST be high. 3 - 1 BPD2 - 0 Block Programming Data These bits refer to the value to be loaded into the connection memory, whenever the memory block programming feature is activated. After the MBPE bit in the Control Register is set to high and the MBPS bit in this register is set to high, the contents of the bits BPD2 - 0 are loaded into bits 2 - 0 of the Connection Memory Low. Bits 15 - 3 of the Connection Memory Low and bits 15 - 0 of Connection Memory High are zeroed.
