12.1
This LSI of microprocessors includes an on-chip 32-bit timer unit (TMU). The TMU of the
SH7750 or SH7750S has three 32-bit timer channels (channels 0 to 2), and the TMU of the
SH7750R has five channels (channels 0 to 4).
12.1.1
The TMU has the following features.
• Auto-reload type 32-bit down-counter provided for each channel
• Input capture function provided in channel 2
• Selection of rising edge or falling edge as external clock input edge when external clock is
• 32-bit timer constant register for auto-reload use, readable/writable at any time, and 32-bit
• For channels 0 to 2, selection of seven counter input clocks for each channel
• For channels 3 and 4, selection is made among five internal clocks (SH7750R only).
• Channels 0 to 2 can also operate in module standby mode when the on-chip RTC output clock
• Two interrupt sources
• DMAC data transfer request capability
selected or input capture function is used
down-counter provided for each channel
External clock (TCLK), on-chip RTC output clock, five internal clocks (Pck/4, Pck/16, Pck/64,
Pck/256, Pck/1024) (Pck is the peripheral module clock)
is selected as the counter input clock; that is, timer operation continues even when the clock
has been stopped for the TMU.
Timer count operations using an external or internal clock are only possible when a clock is
supplied to the timer unit.
One underflow source (each channel) and one input capture source (channel 2)
On channel 2, a data transfer request is sent to the DMAC when an input capture interrupt is
generated.
