MEASUREMENT REGISTERS

0x40

HSYNC Period MSB, (read

only)

7:0

HSYNC Period MSB

These registers report a 16-bit value containing the number of

crystal clocks inside a 16 consecutive HSYNC period window.

This means the 16-bit number will reflect one HSYNC period

with 1/16 LSB resolution - the last 4 -bits of the measurement

will be fractional.

0x41

HSYNC Period LSB, (read

only)

7:0

HSYNC Period LSB

0x42

HSYNC Width MSB, (read

only)

7:0

HSYNC Width MSB

These registers report a 16-bit value containing the number of

crystal clocks inside 16 consecutive HSYNC pulses. This

means the 16-bit number will reflect one HSYNC pulse width

with 1/16 LSB resolution - the last 4 bits of the measurement

will be fractional.

0x43
