56 / 80 page  MPC860 Family Hardware Specifications, Rev. 7 56 Freescale Semiconductor CPM Electrical Characteristics 11.7 SCC in NMSI Mode Electrical Specifications Table 20 provides the NMSI external clock timing. Table 21 provides the NMSI internal clock timing. Figure 55 through Figure 57 show the NMSI timings. Table 20. NMSI External Clock Timing Num Characteristic All Frequencies Unit Min Max 100 RCLK1 and TCLK1 width high 1 1 The ratios SYNCCLK/RCLK1 and SYNCCLK/TCLK1 must be greater than or equal to 2.25/1. 1/SYNCCLK — ns 101 RCLK1 and TCLK1 width low 1/SYNCCLK + 5 — ns 102 RCLK1 and TCLK1 rise/fall time — 15.00 ns 103 TXD1 active delay (from TCLK1 falling edge) 0.00 50.00 ns 104 RTS1 active/inactive delay (from TCLK1 falling edge) 0.00 50.00 ns 105 CTS1 setup time to TCLK1 rising edge 5.00 — ns 106 RXD1 setup time to RCLK1 rising edge 5.00 — ns 107 RXD1 hold time from RCLK1 rising edge 2 2 Also applies to CD and CTS hold time when they are used as external sync signals. 5.00 — ns 108 CD1 setup Time to RCLK1 rising edge 5.00 — ns Table 21. NMSI Internal Clock Timing Num Characteristic All Frequencies Unit Min Max 100 RCLK1 and TCLK1 frequency 1 1 The ratios SYNCCLK/RCLK1 and SYNCCLK/TCLK1 must be greater than or equal to 3/1. 0.00 SYNCCLK/3 MHz 102 RCLK1 and TCLK1 rise/fall time — — ns 103 TXD1 active delay (from TCLK1 falling edge) 0.00 30.00 ns 104 RTS1 active/inactive delay (from TCLK1 falling edge) 0.00 30.00 ns 105 CTS1 setup time to TCLK1 rising edge 40.00 — ns 106 RXD1 setup time to RCLK1 rising edge 40.00 — ns 107 RXD1 hold time from RCLK1 rising edge 2 2 Also applies to CD and CTS hold time when they are used as external sync signals. 0.00 — ns 108 CD1 setup time to RCLK1 rising edge 40.00 — ns |
