9.1.3
8-bit timer 1 (TIM1) has two registers, as shown in table 9.1. These registers perform clock
selection and other functions.

Notes: 1. Use word-length writes. Byte and longword writes cannot be used.

9.2.1
The timer 1 counter (T1CNT) is an 8-bit readable/writable* up-counter. When the timer enable bit
(TME) is set to 1 in the timer 1 control/status register (T1CSR), T1CNT starts incrementing on the
internal clock selected by bits CKS2—CKS0 in T1CSR. When the T1CNT value overflows (from
H'FF to H'00), an interval timer interrupt (ITI) is generated.
T1CNT is initialized to H'00 by a hardware reset or when the TME bit is 0.
Note: The method for writing to T1CNT is different from that for general registers to prevent
