Chapter 916-bit TimerControl registers IX - 139.2.3 Programmable Timer RegistersTimer 8 to timer 11 each have 16-bit programmable timer registers. Programmable timer registers are composedof the binary counter (TMnBC), the compare/capture A register (TMnCA) and the compare/capture B register(TMnCB).■ Timer 8 Binary Counter (TM8BC: 0x0000A210) [16-bit Access Register]This is a binary counter of timers and a 16-bit readable only register. Table:9.2.2 shows updated timing (0x0000clear, etc.) of the binary counter.Table:9.2.2 The Updated Timing of Binary Counter and Update Valuebp 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0Flag TMBC15TMBC14TMBC13TMBC12TMBC11TMBC10TMBC9TMBC8TMBC7TMBC6TMBC5TMBC4TMBC3TMBC2TMBC1TMBC0At reset 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Access R R R R R R R R R R R R R R R RTMCLE flag (TMnMD)=0 TMCLE flag (TMnMD)=1When initializing a timer (when the TMLDEflag of the TMnMD register is set to “1”)TMnBC←0x0000 TMnBC←0x0000Count clock up (down) TMnBC←TMnBC+1(TMnBC←TMnBC-1)TMnBC←TMnBC+1(TMnBC←TMnBC-1)TMnBC overflow TMnBC←0x0000 TMnBC←0x0000TMnBC underflow TMnBC←0xFFFF TMnBC←0xTMnCACount up (down) from the TMnBC and theTMnCA matchTMnBC←TMnBC+1(TMnBC←TMnBC-1)TMnBC←0x0000Count up (down) from the TMnBC and theTMnCB matchNo change No changeAt the TMnCA capture No change TMnBC←0x0000At the TMnCB capture No change No change
