7.2.17

Diagnostic Blanking Register (Address 0x2B/0x3B)

The 0x3B command is used to program the 6-bit register up/down counter used for blanking

diagnostics. A diagnostic is not reported in the Status Register until the Up/Down Counter has reached

the programmed terminal value (BLANK).

7.2.18

Diagnostic MUX Control (Address 0x2C/0x3C)

The 0x3C command is used to control the pin-to-pin short diagnostic MUX. This register is made up of

two 4-bit registers PLUS[3:0] and MINUS[3:0]. PLUS controls the pin connected to the positive side of

the comparator, MINUS to the negative side. The default value at POR is 0x00FF (all pin-to-pin short

MUXes are OFF).
