qb - rl78g1c(control code : a) release note r20ut2691ej0200 rev.2.00 p age 4 of 5 mar 27, 2014 2.3 details of restriction s no .1 emulation of low - speed operation with usb function module [ description ] if bit 3 of the system configuration control register is set ?1? (dmrpu = ?1?) when using the low - speed operation , d+ is pulled up instead of d - . for that reason, usb function modu le cannot notify the usb host of connection as a low - speed device. [ workaround ] set t he b it 3 of the system configuration control register to ? 0 ? (dmrpu = ? 0 ?) and p ull - up d - line on user system. [ implementation ] this issue has been corrected in cubesuit e+ v2.01.00 and later . no.2 supplying negative reference voltage to the a/d converter [ description ] the following difference occur s between the target device and iecube about the analog reference voltage minus of the a/d converter. [target device] w hen the adrefm bit o f adm2 register is set to "1", the analog reference voltage minus of the a/d converter is the input voltage of a n avrefm terminal. [iecube] when the adrefm bit o f adm2 register is set to "1", the analog reference voltage minus of the a /d converter is not the input voltage of a n avrefm terminal. the analog reference voltage minus of the a/d converter becomes the same voltage as vss. [ workaround ] there is no workaround [ implementation ] this issue has been corrected in cubesuite+ v2.01.0 0 and later . no.3 the a/d convers ion time when using 8 bit conversion mode [ description ] 8 bit conversion of qb - rl78g1c ends only the sampling time. [ workaround ] there is no workaround [ implementation ] this issue has been corrected in cubesuite+ v2. 01.00 and later . chapter 3. revision history rev. date description page summary 1.00 july 1 9 , 2013 - newly created. 2.00 mar 27, 2014 p4 restriction matter no.1,2,3 was corrected cubesuite+ v 2.01.00 and later.
