• Manufacturer Part Number: r4f2456
• Description: 16-bit Single-chip Microcomputer H8s Family / H8s/2400 Series
• Manufacturer: Renesas Electronics Corporation.

This LSI has two on-chip 16-bit timer pulse units (TPU: unit 0 and unit 1) which each comprises
six 16-bit timer channels, resulting in a total of 12 channels. The functions of unit 0 are listed in
table 11.1, and the functions of unit 1 are listed in table 11.2. The block diagram of unit 0 is shown
in figure 11.1 and the block diagram of unit 1 is shown in figure 11.2.
The descriptions in this section refer to unit 0.
