TN0436 differences cut1 and cut2 doc id 18327 rev 2 6/10 2.2 feature enhancements the list below shows feature enhancements for cut2. nexus - nxss nexus - rdy pin nexus ? ddr mode ? i/o timing dspi enhanced version crc unit - support for additional polynominal aips mprot - enhanced protection features mc_rgm - destructive reset can be triggered by software sscm - easier access to nvm calibration data selftest - reduction of execution time 2.2.1 nexus - nxss the nexus crossbar slave port data trace module for system sram allows to trace all dma/sram accesses. 2.2.2 nexus - rdy pin to increase the transfer rate of the ieee 1149.1 port, an additional pin has been implemented to signal when data are ready to be transferred to and from nrrs. this may eliminate the need to poll nrrs for status information for synchronization purposes. this capability becomes especially important when performing read/write access transfers to different speed target memories. this functionality is only available on bga257 package (ball k3). rdy is muxed with gpio (gpio is default out of reset). 2.2.3 nexus - ddr mode ? i/o timing the i/o timing has been changed so that the mdo / mseo outputs are valid during the mcko rising and falling edges. 2.2.4 dspi - enhanced version support higher net through put in slave mode by reducing required dead cycles in back to back operation. 2.2.5 crc unit - support for additional polynominal an additional 8-bit crc polynomial has been implemented. the bit field 28:29 of the register crc_cfg for each context selects the polynomial preserving compatibility with previous versions of this ip used on cut1. 2.2.6 aips mprot - enhanced protection features the default reset mprot (master protection) configuration for each aips bridge is determined via the aips_rstcfg vector which has been changed.
TN0436 differences cut1 and cut2 doc id 18327 rev 2 7/10 in general in both modes of operation only the two cores (instruction port, load/store port and the nexus subsystem) have access rights to the ips peripherals per default configuration. 2.2.7 mc_rgm - destructive reset can be triggered by software additional support for software triggerable destructive reset event (d[14]) has been implemented. 2.2.8 sscm - easier access to nvm calibration data the selftest execution time has been reduced compared to cut1 by appr. 13 ms. the information is documented in the spc56el60l3, spc56el60l5 datasheet (see appendix a: reference document ) as part of the reset sequence specification. 2.3 device id codes spc56el60xx contains id codes which identify the device. jtag id cut1: 0000_1010_1110_1010__0010_0000_0100_0001 cut2: 0000_1010_1110_1010__0011_0000_0100_0001 mcu id register 1 (midr1) mcu id register 2 (midr2) the values of these id codes differ between cut1 and cut2. 2.4 pin muxing spc56el60xx cut2 is pin-compatible with cut1. cut2 specifies an additional rdy pin for the bga257 package (ball k3). on cut1 this ball is not connected to any function. the rdy pin on cut2 is muxed with gpio (gpio is default out of reset).
