10.1
The SH7050 series has an on-chip advanced timer unit (ATU) with one 32-bit timer channel and
nine 16-bit timer channels.
10.1.1
ATU features are summarized below.
Capability to process up to 34 pulse inputs and outputs
Prescaler
Channel 0 has four 32-bit input capture lines, allowing the following operations:
Channels 1 and 2 have a total of eight 16-bit input capture/output compare registers and one
dedicated input capture register. The 16-bit output compare registers can also be selected for
channel 10 one-shot pulse offset.
Channels 3 to 5 have a total of ten 16-bit input capture/output compare/PWM registers (ten
inputs/outputs when using input capture/output compare, seven outputs when using PWM),
allowing the following operations:
Input clock to channel 0 scaled in 1 stage, input clock to channels 1 to 9 scaled in 2 stages
1/1 to 1/32 clock scaling possible in initial stage for all channels
1/1, 1/2, 1/4, 1/8, 1/16, or 1/32 scaling possible in second stage for channels 1 to 10
External clock TCLKA, TCLKB selection also possible for channels 1 to 5
Rising-edge, falling-edge, or both-edge detection selectable
Channel 1 compare-match can be used as capture signal (TRG1A) (ICR0A, ICR0D only)
Interrupt can be generated by trigger input
Interval interrupt generation function generates four interval interrupts as selected
Waveform output by means of compare-match: Selection of 0 output, 1 output, or toggle
output
Input capture function: Rising-edge, falling-edge, or both-edge detection
OSBR trigger source is channel 0 capture set to 1 (TRG0A)
Eight counter overflow interrupts/compare-match interrupts/capture interrupts can be
generated (channel 1/A–F, channel 2/A, B)
Compare-match signal (TRG1A) can be sent from channel 1 to channel 0 as a trigger
Compare-match signal can be sent from channel 2 to the advanced pulse controller (APC)
Selection of input capture, output compare, PWM mode
