HSYNCOE — VSYNCO Enable
This bit is set to configure the PTE1/HSYNCO pin for HSYNCO output
function. Reset clears this bit.
1 = PTE1/HSYNCO pin configured as HSYNCO pin
0 = PTE1/HSYNCO pin configured as standard I/O pin
VSYNCOE — VSYNCO Enable
This bit is set to configure the PTE2/VSYNCO pin for VSYNCO output
function. Reset clears this bit.
1 = PTE2/VSYNCO pin configured as VSYNCO pin
0 = PTE2/VSYNCO pin configured as standard I/O pin
SOGE — SOG Enable
This bit is set to configure the PTE0/SOG/TCH0 pin for SOG output
function. Reset clears this bit.
1 = PTE0/SOG/TCH0 pin configured as SOG pin
0 = PTE0/SOG/TCH0 pin configured as standard I/O or TCH0 pin.
TCH0 function is configured by ELS0B and ELS0A bits in
TSC0 (bits 3 and 2 in $0010).
