Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
Notes: 1. Only the values of bits A27–A24 and A8–A0 are valid; bits A23–A9 are ignored. For
10.2
10.2.1
The timer start register (TSTR) is an eight-bit read/write register that starts and stops the timer
counters (TCNT) of channels 0–4. TSTR is initialized to H'E0 or H'60 by a reset and in standby
mode.
Note: * Undefined
Bits 7–5—Reserved: Cannot be modified. Bit 7 is read as undefined. Bits 6 and 5 are always read
as 1. The write value to bit 7 should be 0 or 1, and the write value to bits 6 and 5 should always be
1.
Bit 4—Count Start 4 (STR4): STR4 starts and stops TCNT4.
