FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
High Side Control Register - HSCR
This register controls the operation of the high side drivers.
Writing to this register returns the High Side Status Register
(HSSR).
Table 19. High Side Control Register - $6
0 = Normal
Timing Control Register - TIMCR
This register allows to configure the watchdog, the cyclic
sense and Forced Wake-up periods. Writing to the Timing
Control Register (TIMCR) will also return the Watchdog

high side switch must be enabled (HSx bit).
1 = PWMIN input controls HSx output.
0 = HSx is controlled only by SPI.
HSx - HSx Switch Control.
This write-only bit enables/disables the corresponding
high side switch.
1 = HSx switch on.
0 = HSx switch off.
High Side Status Register - HSSR
This register returns the status of the high side switches
and is also returned when writing to the HSCR.
Table 20. High Side Status Register - $6/$7
CS/WD - Cyclic Sense or Watchdog prescaler select
This write-only bit selects which prescaler is being written
to, the Cyclic Sense/Forced Wake-up prescaler or the
Watchdog prescaler.
1 = Cyclic Sense/Forced Wake-up Prescaler selected
0 = Watchdog Prescaler select
WDx - Watchdog Prescaler
This write-only bits selects the divider for the watchdog
prescaler and therefore selects the watchdog period in
accordance with Table 22 . This configuration is valid only if
windowing watchdog is active.

High Side thermal shutdown
A thermal shutdown of the high side drivers is indicated by
setting all HSxOP and HSxCL bits simultaneously.

0 = Normal
HSxCL - High Side Current Limitation
This read-only bit indicates that the respective high side
switch is operating in current limitation mode.
1 = HSx in current limitation (or thermal shutdown)
CYSTx - Cyclic Sense Period Prescaler Select
This write-only bits selects the interval for the wake-up
cyclic sensing together with the bit CYSX8 in the
Configuration Register (CFR) (see page 44 ).
This option is only active if one of the high side switches is
enabled when entering in Stop or Sleep mode. Otherwise, a
timed wake-up is performed after the period shown in
