Watch Dog Reset Status (Initial Value 0, RW1C)
Indicates that a watchdog reset has occurred (refer to Section
12.3.6).
Initialized when CGRESET* is asserted.
0 = No watchdog reset has occurred.
1 = A watchdog reset has occurred
Watch Dog Reset External Enable (Initial Value 0, R/W)
Specifies whether to assert the WDRST* signal at a watchdog
reset (refer to Section 12.3.6).
Initialized when CGRESET* is asserted.
0 = Do not assert the WDRST* signal.
1 = Assert the WDRST* signal.
Set to 1 at a reset if the corresponding DATA[15:8] signal is
high.
Set to 0 at a reset if the corresponding DATA[15:8] signal is
low.
Specifies the number of G-Bus clock (GBUSCLK) cycles after
which a bus timeout error will occur on the internal bus (G-
Bus) of the TX4937.
11 = 4096 GBUSCLK
10 = 2048 GBUSCLK
01 = 1024 GBUSCLK
00 = 512 GBUSCLK
Indicates a value for indicating whether to enable the
TX49/H3 internal timer interrupt (refer to Section 15.3.5).
H: 0: The TX49/H3 internal timer interrupt is enabled.
L: 1: The TX49/H3 internal timer interrupt is disabled.
