CHAPTER 8 8-BIT TIMERS H0, H1 AND H2
8.1 Functions of 8-Bit Timers H0, H1, and H2
8-bit timers H0, H1, and H2 have the following functions.
• Interval timer
• Square-wave output^{Note 1}
• PWM output^{Note 2}
• Carrier generator (8-bit timer H1 only)^{Note 3}
Notes 1.
2.
3.
TMH0 and TMH1 only.
However, TOH0 and TOH1 only for TOHn
TMH1 only. TM51 and TMH1 can be used in combination as a carrier generator mode.
8.2 Configuration of 8-Bit Timers H0, H1, and H2
8-bit timers H0, H1, and H2 include the following hardware.

8-bit timer H compare register 0n (CMP0n)
8-bit timer H compare register 1n (CMP1n)
TOHn^{Note 1}, output controller
Control registers
8-bit timer H mode register n (TMHMDn)
8-bit timer H carrier control register 1 (TMCYC1)^{Note 2}
Port mode register 3 (PM3)
Port register 3 (P3)
Notes 1. TMH2 does not have an output pin (TOH2). It can only be used as an internal interrupt
(INTTMH2) or an external event input enable signal for the TI52 pin.
2. 8-bit timer H1 only
Remark n = 0-2, however, TOH0 and TOH1 only for TOHn
Figures 8-1 and 8-3 show the block diagrams.
