Hi all,
I am referring MC9S12ZVM-Family RM.(Rev 2.13)
In the chapter 1.13.8.2.1 Bootstrap Precharge
The below chunk of data :
***********************************************************Start**********************************************************
The bootstrap capacitors must be precharged before turning on the high-side drivers for the first time. This
can be done by using the PMF software output control mechanism:
PMFOUTC = 0x3F; // SW control on all outputs
PMFOUTB = 0x2A; // All high-sides off, all low-sides on
The PWM0 signals should be configured to start with turning on the low-side before the high-side drivers
in order to assure precharged bootstraps. Therefore invert the PWM0 signals:
PMFCINV = 0x3F; // Invert all channels to precharge
*********************************************************End*************************************************************
Query is whether the above advisory of pre-charging bootstrap and inverting PWM0 signals is applicable for all versions of GDU i.e. GDUV4, GDUV5, GDUV6 or for a specific version
Thanking in advance
