user?s manual u17272ej1v0um 33 chapter 4 restrictions the following restrictions a pply to the QB-78K0SKX1MINI. { clock oscillation or clock input via a resonator on the tar get system is not supported. the clock differs between the device and the tool (QB-78K0SKX1MINI) according to the option byte (oscsel1, oscsel0) setting as follows. oscsel1 oscsel0 device tool 0 0 crystal/ceramic oscillation clock clock on qb-78k0smini 0 1 external clock input clock on qb-78k0smini 1 x high-speed ring-osc clock high-speed ring-osc clock { the low-speed ring-osc clock emulates at 250 khz. { the QB-78K0SKX1MINI has 256 kb of ram. however, the 256 kb ram area can be accessed normally from the user program even when a 128 kb device is being em ulated, so be aware that problems such as stack overflow may occur without your knowledge. { the characteristics of the ad converter, lvi, and po rts are not fully equivalent to those of the device. pull-down resistors have also been inserted at t he port signals to protect the target i/f. see appendix a target interface equivalent circuit for details. { av ss and v ss are equivalent on the QB-78K0SKX1MINI. { when using the QB-78K0SKX1MINI, a correct ad conver sion result can be obtained even without waiting for 1 s to elapse after setting bit 0 (adce) of the a/d converte r mode register (adm) to 1. when using the actual device, however, be sure to execute processi ng such as reading and discarding this result. { the internal functions (regi sters, peripheral macro, multiplier, etc. ) of the qb-78k0skx1-da always operate for the 78k0s/kb1+. therefore, while t he emulation is performed for 78k0s/ka1+, ku1+, or ky1+, if the bit of the register which exists only in the 78k0s/kb1+ is accessed from the program, it can be read or written even if access to the bit is disabled under normal conditions. the multiplication instruction execution is enabled while the emulation is performed for 78k0s/ka1+, ku1+, and ky1+.
user?s manual u17272ej1v0um 34 appendix a target interface equivalent circuit this chapter explains the differences between the signal lines of the ta rget interface circuit of the qb- 78k0skx1mini and the signal lines of the target device. although the target device is a cmos circuit, the target interface circui t of the QB-78K0SKX1MINI consists of an emulation circuit that depends on the emulation cpu, ttl, cmos-ic, etc. when the target system is debugged by co nnecting it to the QB-78K0SKX1MINI, the QB-78K0SKX1MINI emulates just as if the actual target device were operating on the target system. however, small differences arise because th e QB-78K0SKX1MINI actually is emulating. the target interface equivalent circuit of the QB-78K0SKX1MINI is shown in figure a-1 below. figure a-1. equivalent circuit (1/2) v dd nef31pt222z1e9b (filter) target system side QB-78K0SKX1MINI side 100 k ? av ref nef31pt222z1e9b (filter) 100 k ? ku1+/ky1+ ka1+/kb1+ ev dd av dd v ss av ss d7885 (level shifter) d7885 (level shifter) 33 k ? p00 to p03 p30 to p33 p40 to p47 p120 to p123 emulation cpu (fpga) 1 m ? ev dd 3.3 v ev dd 33 k ?
