36 / 60 page ZL50130 Data Sheet 36 Zarlink Semiconductor Inc. 4.4 System Function Interface All System Function Interface signals are 5 V tolerant. The core of the chip will be held in reset for 16383 SYSTEM_CLK cycles after SYSTEM_RST has gone HIGH to allow the PLL’s to lock. 4.5 Test Facilities 4.5.1 Administration and Control Interface All Administration and Control Interface signals are 5 V tolerant. Signal I/O Package Balls Description SYSTEM_CLK I U6 System Clock Input. The system clock frequency is 100 MHz. The frequency must be accurate to within ±32 ppm in synchronous mode. SYSTEM_RST I V4 System Reset Input. Active low. The system reset is asynchronous, and causes all registers within the ZL50130 to be reset to their default state. SYSTEM_DEBUG I U5 System Debug Enable. This is an asynchronous signal that, when de-asserted, prevents the software assertion of the debug-freeze command, regardless of the internal state of registers, or any error conditions. Active high.

Connected to an internal register, so customer can set user-defined parameters. Bits [4:0] reserved at startup or reset for memory TDL setup. See the ZL50130 Programmers Model for more details. TEST_MODE[2:0] I D [2] AF6 [1] AB9 [0] AC8 Test Mode input - ensure these pins are tied to ground for normal operation. 000 SYS_NORMAL_MODE 001-010 RESERVED 011 SYS_TRISTATE_MODE 100-111 RESERVED Table 10 - Administration/Control Interface Package Ball Definition |
