Table 267. Description of CIU_TestSel2 bits
Bit Symbol Description
7 TstBusFlip If set to logic 1, the internal test bus(D6-D0) is mapped to the external
test bus pins by the following order: D4,D3, D2,D6,D5, D0, D1. See
Section 8.6.21.2 “CIU test bus” on page 141.
6 PRBS9 Starts and enables the PRBS9 sequence according ITU-TO150.
Note: All relevant register to transmit data have to be configured before
entering PRBS9 mode.
Note: The data transmission of the defined sequence is started by the
Transmit command.
5 PRBS15 Starts and enables the PRBS15 sequence according ITU-TO150.
Note: All relevant register to transmit data have to be configured before
entering PRBS15 mode.
Note: The data transmission of the defined sequence is started by the
Transmit command.
4 to 0 TstBusSel[4:0] Selects the test bus source. See Section 8.6.21.2 “
CIU test bus” on
page 141.

Table 269. Description of CIU_TestPinEn bits
Bit Symbol Description
7 to 0 TestPinEn[7:0] Each of the bit enables the output driver for an internal test pin: P70_IRQ
(MSB), RSTOUT_N, P35, P34 / SIC_CLK, P33_INT1, P32_INT0, P31 /
UART_TX, P30 / UART_RX (LSB). DataEn[7] enables P70_IRQ,
DataEn[0] enables P30 / UART_RX.
Note: The data transmission of the defined sequence is started by the
Transmit command.
