Updated Octo-SPI interface in Table 1. STM32H7B3xI features and peripheral

counts.

Updated Figure 2. Power-up/power-down sequence in Section 6.1.6 Power

supply scheme.

Updated HSLV feature description in Section 3.8 General-purpose input/outputs

(GPIOs).

In Section 5 Pin descriptions: updated Table 6. Legend/abbreviations used in the

pinout table; changed SPDIFRX into SPDIFRX1 and updated allSPDIFRX1 pin

names.

Updated Table 19. Voltage characteristics to add VREF+ in the list of external main

supply voltage.

Removed clock frequencies from Table 22. General operating conditions and

added new Section 6.3.1 .

Changed condition for tRSTTEMPO in Table 29. Reset and power control block

characteristics.

IWDG and changed SPDIFRX into SPDIFRX1 in Table 44. Peripheral current

consumption in Run mode.

Table 58. Flash memory programming: updated table title as well as tME

description and unit.

Section 6.3.18 FMC characteristics: changed VOS level to VOS0 in the

parameter measurement conditions and replaced sentence "the TKERCK is the

fmc_ker_ck clock period" by "the Tfmc_ker_ck is the kernel clock period" in the

whole section.

Section 6.3.19 Octo-SPI interface characteristics: added parameter

measurement conditions, updated Table 90. OCTOSPI characteristics in SDR

mode and Table 91. OCTOSPI characteristics in DTR mode (with DQS)/Octal

and Hyperbus, updated Figure 51. OctoSPI Hyperbus clock, Figure 52. OctoSPI

Hyperbus read and Figure 53. OctoSPI Hyperbus write.
