  Timer General Register (TGR) 
The TGR registers are 16-bit readable/writable registers. This module has eighteen TGR registers, 
six for channel 0, two each for channels 1 and 2, four each for channels 3 and 4. 
TGRA, TGRB, TGRC, and TGRD function as either output compare or input capture registers. 
TGRC and TGRD for channels 0, 3, and 4 can also be designated for operation as buffer registers. 
TGR buffer register combinations are TGRA and TGRC, and TGRB and TGRD.  
TGRE_0 and TGRF_0 function as compare registers. When the TCNT_0 count matches the 
TGRE_0 value, an A/D converter start request can be issued. TGRF can also be designated for 
operation as a buffer register. TGR buffer register combination is TGRE and TGRF.
