11.1
The H8/38024 Group is provided with two on-chip 10-bit PWMs (pulse width modulators),
designated PWM1 and PWM2, with identical functions. The PWMs can be used as D/A
converters by connecting a low-pass filter. In this section the suffix m (m = 1 or 2) is used with
register names, etc., as in PWDRLm, which denotes the PWDRL registers for each PWM.
11.1.1
Features of the 10-bit PWMs are as follows.
• Choice of four conversion periods
• Pulse division method for less ripple
• Use of module standby mode enables this module to be placed in standby mode independently
On the H8/38124 Group it is possible to select between two types of PWM output: pulse-division
PWM and event counter PWM (PWM incorporating AEC). (The H8/38024 Group, H8/38024F-
ZTAT Group, and H8/38024S Group can only produce pulse-division PWM output.) Refer to
section 9.7, Asynchronous Event Counter, for information on event counter PWM.
Any of the following conversion periods can be chosen:
4,096/φ, with a minimum modulation width of 4/φ
2,048/φ, with a minimum modulation width of 2/φ
1,024/φ, with a minimum modulation width of 1/φ
512/φ, with a minimum modulation width of 1/2 φ
when not used.
