[Asterisk-Dev] Raising loop current limit on the Proslic (reg.71)

[Alfred R. Nurnberger]

The Silicon Labs application note AN33 for neon flashing sets Vbath to 94.5
V.

Here are the register settings for neon flashing according to AN33 if
someone wants to play with them.

			 Addr		data		comment
---------------------------------------------------------
Indirect registers: 0x16	0x03E8	RNGY = 4hz
			  0x15	0x7BEF	RNGX = 91.5 Vpk
			  0x14	0x009F	RCO

			 Addr		data		comment
---------------------------------------------------------
Direct registers:	 0x22		0x19		Enable timers

			 0x4A		0x3F		Vbath = 94.5V

			 0x30		0xE0		active time = 60ms = 0x01E0
			 0x31		0x01

			 0x32		0xF0		incactive time = 190ms = 0x05F0
			 0x33		0x05

			 0x40		0x04		enable "ringing" = flashing

Careful with how high you push VBat though, they're only 100V caps.
