CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Clock Timer)
4.8.5 Programming notes
(1) Be sure to data reading in the order of low-order data (TM0–TM3) then high-order data (TM4–TM7).
(2) When the clock timer has been reset, the interrupt factor flag (IT) may sometimes be set to "1". Conse-
quently, perform flag reading (reset the flag) as necessary at reset.
(3) Reading of interrupt factor flags is available at EI, but be careful in the following cases.
If the interrupt mask register value corresponding to the interrupt factor flags to be read is set to "1", an
interrupt request will be generated by the interrupt factor flags set timing, or an interrupt request will
not be generated.
