16-Bit Reload Timers 0 and 1 (With Event Count Function)
The 16-bit reload timers have the following functions.
The count clock can be selected from three internal clocks or the external event clock.
An interrupt to the CPU can be generated when an underflow occurs on 16-bit reload timer 0 or 1. This interrupt
allows the timers to be used as interval timers.
Two different operation modes can be selected when an underflow occurs on 16-bit reload timer 0 or 1: one-
shot mode in which timer operation halts when an underflow occurs or reload mode in which the value in the
reload register is loaded into the timer and counting continues.
Extended intelligent I/O service (EI2OS) is supported.
The MB90560/565 series contains two 16-bit reload timer channels.
16-bit reload timer operation modes
Interval times for the 16-bit reload timers
Note : The values enclosed in ( ) and the example of interval times is for a machine clock frequency of 16 MHz.
φ is the machine clock frequency value for the calculation.
Remarks : 16-bit reload timer 0 can be used to generate the baud rate for UART0.
16-bit reload timer 1 can be used to generate the baud rate for UART1 and activation trigger for the
A/D converter.
