(1) there is no wait corresponding to one subsystem clock when halt is released. because the clock mounted in the ie system is used, the x4 subsystem clock is supplied to the peripheral functions even during halt. (2) there is no oscillation stabilization time when reset is released. immediately after reset is released, the cpu starts operating. (3) the subsystem clock on the target system cannot be emulated. use the subsystem clock on the emulation board for emulation. user?s manual u16431ej1v0um 34 appendix a emulation probe pin assignment table table a-1. np-h64gb-tq pin assignments emulation probe tgcn1 pin no. emulation probe tgcn1 pin no. 1 108 33 14 2 107 34 13 3 104 35 18 4 103 36 17 5 100 37 22 6993821 7943928 8934027 9304192 10 29 42 91 11 24 43 98 12 23 44 97 13 20 45 102 14 19 46 101 15 16 47 106 16 15 48 105 17 43 49 77 18 44 50 78 19 47 51 73 20 48 52 74 21 51 53 69 22 52 54 70 23 57 55 63 24 58 56 64 25 59 57 61 26 60 58 62 27 55 59 65 28 56 60 66 29 49 61 71 30 50 62 72 31 45 63 75 32 46 64 76 remarks 1. np-h64gb-tq is a product of naito densei machida mfg. co., ltd. 2. the numbers in the ?emulation probe? column indicate the corresponding pin number on the emulation probe tip. user?s manual u16431ej1v0um 35 appendix b notes on target system design the following shows the conditions when connecting the emulation probe to the conversion adapter. follow the configuration below and consider the shape of parts to be mounted on the target system when designing a system. among the products described in this appendix, np-h64gb-tq is a product of naito densei machida mfg. co., ltd, and tgb-064sdp is a product of tokyo eletech corporation. table b-1. distance between ie system and conversion adapter emulation probe conversion adapter distance between ie system and conversion adapter np-h64gb-tq tgb-064sdp 370 mm figure b-1. distance between in-circuit emulator and conversion socket/conversion adapter (when 64gb is used) 370 mm note in-circuit emulator ie-78k0s-ns or ie-78k0s-ns-a emulation board IE-789882-NS-EM1 conversion adapter: tgb-064sdp target system tgcn1 emulation probe np-h64gb-tq appendix b notes on target system design user ? s manual u16431ej1v0um 36 figure b-2. connection conditions of target system (when np-h64gb-tq is used) emulation probe np-h64gb-tq emulation board IE-789882-NS-EM1 42.6 mm 45 mm target system conversion adapter tgb-064sdp 16 mm 21.4 mm 16 mm 11 mm |
