4.12 16-Bit Timer Control Registers
Table 4-6 shows the registers used to control the 16-bit timers. A binary counter
(TMnBC), a compare/capture register A (TMnCA), a compare/capture register B
(TMnCB), and a timer mode register (TMnMD) is associated with each 16-bit
timer.
TM4BC/TM5BC: Timer n Binary Counter x’00FE82’/x’00FE92’
TMnCA and TMnCB are 16-bit
access registers. Use the MOV
instruction to write to them.
TM4CA/TM5CA: Timer n Compare/Capture Register A x’00FE84’/x’00FE94’
TM4CB/TM5CB: Timer n Compare/Capture Register B x’00FE88’/x’00FE98’
Table 4-6 16-Bit Timer Control Registers
Register Address R/W Description
Timer 4 TM4MD x’00FE80’ R/W Timer 4 mode register
TM4BC x’00FE82’ R Timer 4 binary counter
TM4CA x’00FE84’ R/W Timer 4 compare/capture register A
TM4CAX x’00FE86’ — Timer 4 compare/capture register set AX
TM4CB x’00FE88’ R/W Timer 4 compare/capture register B
TM4CBX x’00FE8A’ — Timer 4 compare/capture register set BX
Timer 5 TM5MD x’00FE90’ R/W Timer 5 mode register
TM5BC x’00FE92’ R Timer 5 binary counter
TM5CA x’00FE94’ R/W Timer 5 compare/capture register A
TM5CAX x’00FE96’ — Timer 5 compare/capture register set AX
TM5CB x’00FE98’ R/W Timer 5 compare/capture register B
TM5CBX x’00FE9A’ — Timer 5 compare/capture register set BX
Note: TM4CAX, TM4CBX, TM5CAX, and TM5CBX are virtual registers used only
in double-buffer mode during PWM output. They do not exist in the hardware
and are not readable or writable. Depending on the write signal, they load the
value in the associated CA or CB register.
