105 / 138 page  MPC5644A Microcontroller Data Sheet, Rev. 7 Freescale Semiconductor 105 N Table 40. Nexus debug port operating frequency Package Nexus Width Nexus Routing Nexus Pin Usage Max. Operating Frequency MDO[0:3] MDO[4:11] CAL_MDO[4:1 1] 176 LQFP 208 BGA 324 BGA Reduced port mode1 1 NPC_PCR[FPM] = 0 Route to MDO2 2 NPC_PCR[NEXCFG] = 0 Nexus Data Out [0:3] GPIO GPIO 40 MHz3 3 The Nexus AUX port runs up to 40 MHz. Set NPC_PCR[MCKO_DIV] to divide-by-two if the system frequency is greater than 40 MHz. Full port mode4 4 NPC_PCR[FPM] = 1 Route to MDO2 Nexus Data Out [0:3] Nexus Data Out [4:11] GPIO 40 MHz5,6 5 Set the NPC_PCR[MCKO_DIV] to divide by two if the system frequency is between 40 MHz and 80 MHz inclusive. Set the NPC_PCR[MCKO_DIV] to divide by four if the system frequency is greater than 80 MHz. 6 Pad restrictions limit the Maximum Operation Frequency in these configurations 496 CSP Reduced port mode1 Route to MDO2 Nexus Data Out [0:3] GPIO GPIO 40 MHz3 Full port mode4 Route to MDO2 Nexus Data Out [0:3] Nexus Data Out [4:11] GPIO 40 MHz5,6 Route to CAL_MDO7 7 NPC_PCR[NEXCFG] = 1 Cal Nexus Data Out [0:3] GPIO Cal Nexus Data Out [4:11] 40 MHz3 |
