C.1.2 CHI Programming Options

CMS = clock mode select

0 = line rate

1 = 2X line rate

XEN = transmitter enable

0 = disable (DX tri-stated)

1 = enable (DX driven during active time slots)

= frame edge select

0 = falling edge

1 = rising edge

XCE = CLKXR output edge select for DX

0 = falling edge

1 = rising edge

RCE = CLKXR input edge select for DR

0 = falling edge

1 = rising edge

XBOFF = 3-bit transmit output bit offset

000-1111= CLKXR (or 2xCLKXR) delay from FS to DX bit0

RBOFF = 3-bit receive input bit offset

000-111 = CLKXR (or 2xCLKXR) delay from FS to DR bit0

XTS = 6-bit transmit output TS offset

00-3F = CLKXR (or 2xCLKXR) TS delay from FS to DX bit0

RTS = 6-bit receive input TS offset

00-3F = CLKXR (or 2xCLKXR) TS delay from FS to DR bit0

Bt8370 only supports CHI and GCI buses if N = 24, 32 or 48, although either

bus is defined to operate at Nx64 from N = 4 to N = 48. Bt8370 does not support

AT&T's Dual CHI (separate A/B buses) or K2 buses, nor does it support INTEL's

SLD (ping/pong) 3-pin bus.
